EulerOS 2.0 SP13 : glibc (EulerOS-SA-2026-1272)

high Nessus Plugin ID 301573

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 Passing too large an alignment to the memalign suite of functions (memalign, posix_memalign, aligned_alloc) in the GNU C Library version 2.30 to 2.42 may result in an integer overflow, which could consequently result in a heap corruption.Note that the attacker must have control over both, the size as well as the alignment arguments of the memalign function to be able to exploit this. The size parameter must be close enough to PTRDIFF_MAX so as to overflow size_t along with the large alignment argument.
 This limits the malicious inputs for the alignment for memalign to the range [162+ 1, 163] and exactly 163 for posix_memalign and aligned_alloc.Typically the alignment argument passed to such functions is a known constrained quantity (e.g. page size, block size, struct sizes) and is not attacker controlled, because of which this may not be easily exploitable in practice. An application bug could potentially result in the input alignment being too large, e.g. due to a different buffer overflow or integer overflow in the application or its dependent libraries, but that is again an uncommon usage pattern given typical sources of alignments.(CVE-2026-0861)

 Calling wordexp with WRDE_REUSE in conjunction with WRDE_APPEND in the GNU C Library version 2.0 to version 2.42 may cause the interface to return uninitialized memory in the we_wordv member, which on subsequent calls to wordfree may abort the process.(CVE-2025-15281)

Tenable has extracted the preceding description block directly from the EulerOS glibc security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected glibc packages.
