A vulnerability, which was classified as problematic, was found in Heimdal (unknown version). Affected is an unknown code block of the component Fix CVE-2022-3437. The manipulation with an unknown input leads to a integrity check vulnerability. CWE is classifying the issue as CWE-354.

This may prevent it from detecting if the data has been modified or corrupted in transmission. This is going to have an impact on integrity. CVE summarizes:

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.
