|Gentoo Linux Security Advisory
Title: Heimdal: Arbitrary code execution (GLSA 201202-05)
Date: February 22, 2012
A boundary error in Heimdal could result in execution of arbitrary
Heimdal is a free implementation of Kerberos 5.
Vulnerable: < 1.5.1-r1
Unaffected: >= 1.5.1-r1
Architectures: All supported architectures
A boundary error in the "encrypt_keyid()" function in
appl/telnet/libtelnet/encrypt.c of the telnet daemon and client could
cause a buffer overflow.
An unauthenticated remote attacker may be able to execute arbitrary code
with the privileges of the user running the telnet daemon or client, or
cause Denial of Service.
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-1.5.1-r1"
