Synopsis ========
Buffer overflow vulnerabilities have been found in the telnet client in Heimdal which could lead to execution of arbitrary code.
Background ==========
Heimdal is a free implementation of Kerberos 5 that includes a telnet client program.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/heimdal < 0.6.4 >= 0.6.4
Description ===========
Buffer overflow vulnerabilities in the slc_add_reply() and env_opt_add() functions have been discovered by Gael Delalleau in the telnet client in Heimdal.
Impact ======
Successful exploitation would require a vulnerable user to connect to an attacker-controlled host using the telnet client, potentially executing arbitrary code with the permissions of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Heimdal users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-crypt/heimdal-0.6.4"
