Heap overflow
A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrapdes and unwrapdes3 routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc allocated memory when presented with a...

CVE-2022-3437
CVE-2022-3437 is a heap-based buffer overflow in Samba’s use of Heimdal GSSAPI (unwrap_des/unwrap_des3). The fix involved making memcmp constant-time and patching a compiler-related issue by adding “!= 0” to memcmp results; backported patches were applied to heimdal-7.7.1 and 7.8.0 branches (and ...

PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC kadmind or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow) and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug."
