Summary

musl security update

Details

musl is an implementation of the C standard library built on top of the Linux system call API, including interfaces defined in the base language standard, POSIX, and widely agreed-upon extensions. It is lightweight, fast, simple, free, and strives to be correct in the sense of standards conformance and safety.

Security Fix(es):

musl libc 0.9.13 through 1.2.5 before 1.2.6 has an out-of-bounds write vulnerability when an attacker can trigger iconv conversion of untrusted EUC-KR text to UTF-8.(CVE-2025-26519)

Severity

8.1 (High)
