 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3213-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb November 29, 2022 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : krb5 Version : 1.17-3+deb10u5 CVE ID : CVE-2022-42898 Debian Bug : 1024267

 It was discovered that there was a potential Denial of Service (DoS) attack against krb5, a suite of tools implementing the Kerberos authentication system. An integer overflow in PAC parsing could have been exploited if a cross-realm entity acted maliciously.

 For Debian 10 buster, this problem has been fixed in version 1.17-3+deb10u5.

 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

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the krb5-admin-server packages.
