|Gentoo Linux Security Advisory
Title: Heimdal: Multiple local privilege escalation vulnerabilities (GLSA 200608-21)
Date: August 23, 2006
Certain Heimdal components, ftpd and rcp, are vulnerable to a local privilege escalation.
Heimdal is a free implementation of Kerberos 5.
Vulnerable: < 0.7.2-r3
Unaffected: >= 0.7.2-r3
Architectures: All supported architectures
The ftpd and rcp applications provided by Heimdal fail to check the return value of calls to seteuid().
A local attacker could exploit this vulnerability to execute arbitrary code with elevated privileges.
There is no known workaround at this time.
All Heimdal users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-crypt/heimdal-0.7.2-r3"
