Echo: glibc: security update to 2.41-12+deb13u1+e1

high Tenable Cloud Security Plugin ID 459388

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 [1<<62+ 1, 1<<63] and exactly
 1<<63 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)

Solution

Update the glibc library and its related packages to version 2.41-12+deb13u1+e1 or later.
