CVE-2007-2442: Canonical Ubuntu Linux

High severity, CVSS 10.0. EPSS: 11.4% chance of exploitation in the next 30 days.

The gssrpc__svcauth_gssapi function in the RPC library in MIT Kerberos 5 (krb5) 1.6.1 and earlier might allow remote attackers to execute arbitrary code via a zero-length RPC credential, which causes kadmind to free an uninitialized pointer during cleanup.

Affected products

• Canonical Ubuntu Linux: version 6.06 only; version 6.10 only; version 7.04 only
• Debian Debian Linux: version 3.1 only; version 4.0 only
• Mit Kerberos 5: up to and including 1.6.1
