CVE-2022-42898 not yet assigned priority: Debian including 3 source packages (heimdal, krb5, samba), 15 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 14, open 1.
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."
