| CVE-2018-19591 | 2 Fedoraproject, Gnu | 2 Fedora, Glibc | 2025-12-03 | 7.5 High |
| In the GNU C Library (aka glibc or libc6) through 2.28, attempting to resolve a crafted hostname via getaddrinfo() leads to the allocation of a socket descriptor that is not closed. This is related to the if_nametoindex() function. | ||||
| CVE-2021-20232 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Gnutls, Enterprise Linux | 2025-12-03 | 9.8 Critical |
| A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. | ||||
| CVE-2021-20197 | 4 Broadcom, Gnu, Netapp and 1 more | 6 Brocade Fabric Operating System Firmware, Binutils, Cloud Backup and 3 more | 2025-12-03 | 6.3 Medium |
| There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink. | ||||
| CVE-2022-2509 | 4 Debian, Fedoraproject, Gnu and 1 more | 4 Debian Linux, Fedora, Gnutls and 1 more | 2025-12-02 | 7.5 High |
| A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. | ||||
| CVE-2021-3999 | 4 Debian, Gnu, Netapp and 1 more | 16 Debian Linux, Glibc, E-series Performance Analyzer and 13 more | 2025-12-02 | 7.8 High |
| A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system. | ||||
| CVE-2025-32990 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 6.5 Medium |
| A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. | ||||
| CVE-2025-32989 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 5.3 Medium |
| A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly. | ||||
| CVE-2025-32988 | 2 Gnu, Redhat | 9 Gnutls, Ceph Storage, Discovery and 6 more | 2025-12-01 | 6.5 Medium |
| A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. | ||||
| CVE-2024-5742 | 2 Gnu, Redhat | 2 Nano, Enterprise Linux | 2025-11-21 | 6.7 Medium |
| A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions of the running user provides a window of opportunity for attackers to escalate privileges through a malicious symlink. | ||||
| CVE-2023-7216 | 2 Gnu, Redhat | 2 Cpio, Enterprise Linux | 2025-11-21 | 5.3 Medium |
| A path traversal vulnerability was found in the CPIO utility. This issue could allow a remote unauthenticated attacker to trick a user into opening a specially crafted archive. During the extraction process, the archiver could follow symlinks outside of the intended directory, which allows files to be written in arbitrary directories through symlinks. | ||||
| CVE-2025-1125 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-11-20 | 6.7 Medium |
| When reading data from a hfs filesystem, grub's hfs filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffers size, however it misses to properly check for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculation to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result the hfsplus_open_compressed_real() function will write past of the internal buffer length. This flaw may be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution by-passing secure boot protections. | ||||
| CVE-2025-0689 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-11-20 | 6.7 Medium |
| When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size which is not guaranteed. A crafted filesystem image may lead to a heap-based buffer overflow resulting in critical data to be corrupted, resulting in the risk of arbitrary code execution by-passing secure boot protections. | ||||
| CVE-2025-0685 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-11-20 | 6.4 Medium |
| A flaw was found in grub2. When reading data from a jfs filesystem, grub's jfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_jfs_lookup_symlink() function will write past the internal buffer length during grub_jfs_read_file(). This issue can be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution, by-passing secure boot protections. | ||||
| CVE-2025-0686 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-11-20 | 6.4 Medium |
| A flaw was found in grub2. When performing a symlink lookup from a romfs filesystem, grub's romfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_romfs_read_symlink() may cause out-of-bounds writes when the calling grub_disk_read() function. This issue may be leveraged to corrupt grub's internal critical data and can result in arbitrary code execution by-passing secure boot protections. | ||||
| CVE-2025-0684 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-11-20 | 6.4 Medium |
| A flaw was found in grub2. When performing a symlink lookup from a reiserfs filesystem, grub's reiserfs fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the grub_reiserfs_read_symlink() will call grub_reiserfs_read_real() with a overflown length parameter, leading to a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and can result in arbitrary code execution, by-passing secure boot protections. | ||||
| CVE-2025-0678 | 2 Gnu, Redhat | 4 Grub2, Enterprise Linux, Openshift and 1 more | 2025-11-20 | 7.8 High |
| A flaw was found in grub2. When reading data from a squash4 filesystem, grub's squash4 fs module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size, however, it improperly checks for integer overflows. A maliciously crafted filesystem may lead some of those buffer size calculations to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result, the direct_read() will perform a heap based out-of-bounds write during data reading. This flaw may be leveraged to corrupt grub's internal critical data and may result in arbitrary code execution, by-passing secure boot protections. | ||||
| CVE-2023-4001 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Grub2, Enterprise Linux and 1 more | 2025-11-20 | 6.8 Medium |
| An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package. | ||||
| CVE-2023-4527 | 4 Fedoraproject, Gnu, Netapp and 1 more | 32 Fedora, Glibc, H300s and 29 more | 2025-11-20 | 6.5 Medium |
| A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash. | ||||
| CVE-2024-1048 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Grub2, Enterprise Linux | 2025-11-20 | 3.3 Low |
| A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not be removed and may fill the filesystem when invoked multiple times, resulting in a filesystem out of free inodes or blocks. | ||||
| CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-11-20 | 7.5 High |
| A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
