RHEL Packaging Agent e99e7308eb Fix CVE-2026-47783: SASL timing side-channel in memcached
Backport upstream fix for CVE-2026-47783, a timing side-channel
vulnerability in memcached's SASL password database authentication.
The patch modifies sasl_defs.c to zero the buffer before each fgets
call, use constant-time safe_memcmp() for username and password
comparisons, and remove the early loop break so the entire password
file is always scanned.
