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. The original issue
1097 report stated: 'The latest version of Netatalk (v3.2.0) contains a
security vulnerability. This vulnerability arises due to a lack of
validation for the length field after parsing user-provided data,
leading to an out-of-bounds heap write of one byte (\0). Under specific
configurations, this can result in reading metadata of the next heap
block, potentially causing a Denial of Service (DoS) under certain heap
layouts or with ASAN enabled. ... The vulnerability is located in the
FPLoginExt operation of Netatalk, in the BN_bin2bn function found in
/etc/uams/uams_dhx_pam.c ... if (!(bn = BN_bin2bn((unsigned char *)ibuf,
KEYSIZE, NULL))) ... threads ... [#0] Id 1, Name: 'afpd', stopped
