MIT Kerberos 5: Multiple local privilege escalation vulnerabilities Some applications shipped with MIT Kerberos 5 are vulnerable to local privilege escalation. MIT Kerberos 5 2006-08-10 2006-08-10 143240 local 1.4.3-r3 1.4.3-r3

MIT Kerberos 5 is a suite of applications that implement the Kerberos network protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.

Unchecked calls to setuid() in krshd and v4rcp, as well as unchecked calls to seteuid() in kftpd and in ksu, have been found in the MIT Kerberos 5 program suite and may lead to a local root privilege escalation.

A local attacker could exploit this vulnerability to execute arbitrary code with elevated privileges.

There is no known workaround at this time.

All MIT Kerberos 5 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.4.3-r3"
