Package : krb5 CVE ID : CVE-2024-37370 CVE-2024-37371

Two vulnerabilities were discovered in the GSS message token handling in krb5, the MIT implementation of Kerberos. An attacker can take advantage of these flaws to bypass integrity protections or cause a denial of service.

For the oldstable distribution (bullseye), these problems have been fixed in version 1.18.3-6+deb11u5.

For the stable distribution (bookworm), these problems have been fixed in version 1.20.1-2+deb12u2.

We recommend that you upgrade your krb5 packages.

For the detailed security status of krb5 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/krb5
