Updated heimdal packages fix security vulnerability

The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp. When these patches were backported a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to b...

The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to be inverted.

USN-5936-1: Samba vulnerabilities

Evgeny Legerov discovered that Samba incorrectly handled buffers in certain GSSAPI routines of Heimdal. A remote attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service. CVE-2022-3437 Tom Tervoort discovered that Samba incorrectly used weak rc4-hmac Kerber...
