Description

CVE-2022-43995 affecting package sudo for versions less than 1.9.12p1-1

Sudo 1.8.0 through 1.9.12, with the crypt() password backend, contains a plugins/sudoers/auth/passwd.c array-out-of-bounds error that can result in a heap-based buffer over-read.

The impact could vary depending on the system libraries, compiler, and processor architecture.
