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. • https://security.gentoo.org/glsa/202310-06 https://www.openwall.com/lists/oss-security/2023/02/08/1 • CWE-354: Improper Validation of Integrity Check Value •

Heimdal before 7.7.1 allows attackers to cause a NULL pointer dereference in a SPNEGO acceptor via a preferred_mech_type of GSS_C_NO_OID and a nonzero initial_response value to send_accept. Heimdal anterior a 7.7.1 permite a los atacantes provocar una desreferencia de puntero NULL en un aceptador SPNEGO a través de preferred_mech_type de GSS_C_NO_OID y un valor nonzero initial_response distinto de cero para send_accept. • https://github.com/heimdal/heimdal/commit/f9ec7002cdd526ae84fbacbf153162e118f22580 https://github.com/heimdal/heimdal/security/advisories/GHSA-69h9-669w-88xv https://security.gentoo.org/glsa/202310-06 • CWE-476: NULL Pointer Dereference •

CVSS: 8.8EPSS: 1%CPEs: 7EXPL: 1CVE-2022-42898 – krb5: integer overflow vulnerabilities in PAC parsing
https://notcve.org/view.php?id=CVE-2022-42898
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." El análisis sintáctico de PAC en MIT Kerberos 5 (también conocido como krb5) antes de 1.19.4 y 1.20.x antes de 1.20.1 tiene desbordamientos de enteros que pueden conducir a la ejecución remota de código (en KDC, kadmind, o un servidor de aplicaciones GSS o Kerberos) en plataformas de 32 bits (que tienen un desbordamiento de búfer resultante), y causar una denegación de servicio en otras plataformas. Esto ocurre en krb5_pac_parse en lib/krb5/krb/pac.c. • https://bugzilla.samba.org/show_bug.cgi?id=15203 https://github.com/heimdal/heimdal/security/advisories/GHSA-64mq-fvfj-5x3c https://github.com/krb5/krb5/commit/ea92d2f0fcceb54a70910fa32e9a0d7a5afc3583 https://security.gentoo.org/glsa/202309-06 https://security.gentoo.org/glsa/202310-06 https://security.netapp.com/advisory/ntap-20230216-0008 https://security.netapp.com/advisory/ntap-20230223-0001 https://web.mit.edu/kerberos/advisories https://web.mit.edu/kerberos/krb5-1.19 https://web& • CWE-190: Integer Overflow or Wraparound •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-41916 – Read one byte past a buffer when normalizing Unicode
https://notcve.org/view.php?id=CVE-2022-41916
Heimdal is an implementation of ASN.1/DER, PKIX, and Kerberos. Versions prior to 7.7.1 are vulnerable to a denial of service vulnerability in Heimdal's PKI certificate validation library, affecting the KDC (via PKINIT) and kinit (via PKINIT), as well as any third-party applications using Heimdal's libhx509. Users should upgrade to Heimdal 7.7.1 or 7.8. There are no known workarounds for this issue.
