GLSA-201201-14 : MIT Kerberos 5 Applications: Multiple vulnerabilities

Critical Nessus Plugin ID 57656


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-201201-14 (MIT Kerberos 5 Applications: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in MIT Kerberos 5 Applications:
An error in the FTP daemon prevents it from dropping its initial effective group identifier (CVE-2011-1526).
A boundary error in the telnet daemon and client could cause a buffer overflow (CVE-2011-4862).
Impact :

An unauthenticated remote attacker may be able to execute arbitrary code with the privileges of the user running the telnet daemon or client.
Furthermore, an authenticated remote attacker may be able to read or write files owned by the same group as the effective group of the FTP daemon.
Workaround :

There is no known workaround at this time.


All MIT Kerberos 5 Applications users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/mit-krb5-appl-1.0.2-r1'
