| CVE-2025-32988 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Openshift and 1 more | 2025-08-21 | 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-2023-4527 | 4 Fedoraproject, Gnu, Netapp and 1 more | 32 Fedora, Glibc, H300s and 29 more | 2025-08-21 | 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-2023-4911 | 6 Canonical, Debian, Fedoraproject and 3 more | 40 Ubuntu Linux, Debian Linux, Fedora and 37 more | 2025-08-21 | 7.8 High |
| A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. | ||||
| CVE-2023-5156 | 2 Gnu, Redhat | 2 Glibc, Enterprise Linux | 2025-08-21 | 7.5 High |
| A flaw was found in the GNU C Library. A recent fix for CVE-2023-4806 introduced the potential for a memory leak, which may result in an application crash. | ||||
| CVE-2025-8734 | 1 Gnu | 1 Bison | 2025-08-19 | 3.3 Low |
| A vulnerability has been found in GNU Bison up to 3.8.2. This impacts the function code_free of the file src/scan-code.c. The manipulation leads to double free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The actual existence of this vulnerability is currently in question. The issue could not be reproduced from a GNU Bison 3.8.2 tarball run in a Fedora 42 container. | ||||
| CVE-2025-8733 | 1 Gnu | 1 Bison | 2025-08-19 | 3.3 Low |
| A flaw has been found in GNU Bison up to 3.8.2. This affects the function __obstack_vprintf_internal of the file obprintf.c. Executing manipulation can lead to reachable assertion. The attack requires local access. The exploit has been published and may be used. It is still unclear if this vulnerability genuinely exists. The issue could not be reproduced from a GNU Bison 3.8.2 tarball run in a Fedora 42 container. | ||||
| CVE-2023-4813 | 4 Fedoraproject, Gnu, Netapp and 1 more | 23 Fedora, Glibc, Active Iq Unified Manager and 20 more | 2025-08-18 | 5.9 Medium |
| A flaw was found in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. | ||||
| CVE-2023-4806 | 3 Fedoraproject, Gnu, Redhat | 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more | 2025-08-18 | 5.9 Medium |
| A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags. | ||||
| CVE-2025-45582 | 1 Gnu | 1 Tar | 2025-08-18 | 4.1 Medium |
| GNU Tar through 1.35 allows file overwrite via directory traversal in crafted TAR archives, with a certain two-step process. First, the victim must extract an archive that contains a ../ symlink to a critical directory. Second, the victim must extract an archive that contains a critical file, specified via a relative pathname that begins with the symlink name and ends with that critical file's name. Here, the extraction follows the symlink and overwrites the critical file. This bypasses the protection mechanism of "Member name contains '..'" that would occur for a single TAR archive that attempted to specify the critical file via a ../ approach. For example, the first archive can contain "x -> ../../../../../home/victim/.ssh" and the second archive can contain x/authorized_keys. This can affect server applications that automatically extract any number of user-supplied TAR archives, and were relying on the blocking of traversal. This can also affect software installation processes in which "tar xf" is run more than once (e.g., when installing a package can automatically install two dependencies that are set up as untrusted tarballs instead of official packages). NOTE: the official GNU Tar manual has an otherwise-empty directory for each "tar xf" in its Security Rules of Thumb; however, third-party advice leads users to run "tar xf" more than once into the same directory. | ||||
| CVE-2025-32990 | 2 Gnu, Redhat | 4 Gnutls, Enterprise Linux, Openshift and 1 more | 2025-08-15 | 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 | 4 Gnutls, Enterprise Linux, Openshift and 1 more | 2025-08-15 | 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-2025-1125 | 2 Gnu, Redhat | 3 Grub2, Enterprise Linux, Openshift | 2025-08-12 | 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 | 2025-08-12 | 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-2025-8746 | 1 Gnu | 1 Libopts | 2025-08-12 | 3.3 Low |
| A vulnerability, which was classified as problematic, was found in GNU libopts up to 27.6. Affected is the function __strstr_sse2. The manipulation leads to memory corruption. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. This issue was initially reported to the tcpreplay project, but the code maintainer explains, that this "bug appears to be in libopts which is an external library." This vulnerability only affects products that are no longer supported by the maintainer. | ||||
| CVE-2025-8736 | 1 Gnu | 1 Cflow | 2025-08-12 | 5.3 Medium |
| A vulnerability, which was classified as critical, has been found in GNU cflow up to 1.8. Affected by this issue is the function yylex of the file c.c of the component Lexer. The manipulation leads to buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. | ||||
| CVE-2025-8735 | 1 Gnu | 1 Cflow | 2025-08-12 | 3.3 Low |
| A vulnerability classified as problematic was found in GNU cflow up to 1.8. Affected by this vulnerability is the function yylex of the file c.c of the component Lexer.
