URL: https://advisories.mageia.org/MGASA-2025-0295.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2024-50383

Description:
Botan before 3.6.0, when certain GCC versions are used, has a
compiler-induced secret-dependent operation in lib/utils/donna128.h in
donna128 (used in Chacha-Poly1305 and x25519). An addition can be
skipped if a carry is not set. This was observed for GCC 11.3.0 with -O2
on MIPS, and GCC on x86-i386 (only 32-bit processors can be affected).
