[email protected] reports:

This entry documents the following three vulnerabilities:

Netatalk before 3.2.1 has an off-by-one error and resultant heap-based
buffer overflow because of setting ibuf[len] to ‘\0’ in

are also fixed versions.
Netatalk before 3.2.1 has an off-by-one error, and resultant
heap-based buffer overflow and segmentation violation, because of
incorrectly using FPLoginExt in BN_bin2bn in etc/uams/uams_dhx_pam.c.

metadata of the next heap block, potentially causing a Denial of
Service (DoS) under certain heap layouts or with ASAN enabled. …
