Description

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-5076 advisory.

 - Fix integer overflows in PAC parsing (CVE-2022-42898)

 - Fix CVE-2015-8631, CVE-2015-8630, and CVE-2015-8629
 - the rebase to krb5 1.13.1 in vers 1.13.1-0 also fixed:
 - Bug 1144498 ('Fix the race condition in the libkrb5 replay cache')
 - Bug 1163402 ('kdb5_ldap_util view_policy does not shows ticket flags on s390x and ppc64')
 - Bug 1185770 ('Missing upstream test in krb5-1.12.2: src/tests/gssapi/t_invalid.c')

 In MIT krb5 1.12 and later, when the KDC is configured with PKINIT support, an unauthenticated remote attacker can bypass the requires_preauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line dictionary attack against the user's password.
