NVD Description
Note: Versions mentioned in the description apply only to the upstream botan package and not the botan package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
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.)
