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.Show less

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.Show less

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.Show less

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.Show less

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.Show less

The strncmp implementation optimized for the Power10 processor in the GNU C Library version 2.40 and later writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program.Show less

The strcmp implementation optimized for the Power10 processor in the GNU C Library version 2.39 and later writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program.Show less

A vulnerability classified as critical has been found in GNU Binutils up to 2.44. This affects the function debug_type_samep of the file /binutils/debug.c of the component objdump. 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. It is recommended to apply a patch to fix this issue.Show less

A vulnerability was found in GNU Binutils up to 2.44. It has been rated as critical. Affected by this issue is the function elf_gc_sweep of the file bfd/elflink.c of the component ld. The manipulation leads to memory corruption. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. Upgrading to version 2.45 is able to address this issue. It is recommended to upgrade the affected component.Show less

A vulnerability was found in GNU PSPP 82fb509fb2fedd33e7ac0c46ca99e108bb3bdffb. It has been declared as problematic. This vulnerability affects the function calloc of the file pspp-convert.c.

Untrusted LD_LIBRARY_PATH environment variable vulnerability in the GNU C Library version 2.27 to 2.38 allows attacker controlled loading of dynamically shared library in statically compiled setuid binaries that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as getaddrinfo).Show less
