Title: MIT Kerberos 5: Multiple local privilege escalation vulnerabilities (GLSA 200608-15)
Date: August 10, 2006
Some applications shipped with MIT Kerberos 5 are vulnerable to local privilege escalation.
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.
Vulnerable: < 1.4.3-r3
Unaffected: >= 1.4.3-r3
Architectures: All supported architectures
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"
