AZL-34797 CVE-2022-45142 affecting package heimdal for versions less than 7.8.0-3

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 Wireshark 2.2.0, the Bluetooth L2CAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-btl2cap.c by avoiding use of a seven-byte memcmp for potentially shorter strings...

SUSE CVE-2017-2624

It was found that xorg-x11-server before 1.19.0 including uses memcmp to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp implementations return after an invalid byte is seen, this causes a ti...

SUSE CVE-2018-0733

Because of an implementation bug the PA-RISC CRYPTOmemcmp function is effectively reduced to only comparing the least significant bit of each byte. This allows an attacker to forge messages that would be considered as authenticated in an amount of tries lower than that guaranteed by the security...
