Alpine: multiple musl packages: security update to 1.2.4_git20230717-r6

medium Tenable Cloud Security Plugin ID 440282

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- A security flaw has been discovered in musl libc up to 1.2.6. Affected is the function iconv of the file
src/locale/iconv.c of the component GB18030 4-byte Decoder. Performing a manipulation results in
inefficient algorithmic complexity. The attack must be initiated from a local position. To fix this issue,
it is recommended to deploy a patch. (CVE-2026-6042)

- An issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during
qsort of very large arrays, due to incorrectly implemented double-word primitives. The number of elements
must exceed about seven million, i.e., the 32nd Leonardo number on 32-bit platforms (or the 64th Leonardo
number on 64-bit platforms, which is not practical). (CVE-2026-40200)

Solution

Update the musl library and its related packages to version 1.2.4_git20230717-r6 or later.
