GLSA-200504-04 : mit-krb5: Multiple buffer overflows in telnet client

High Nessus Plugin ID 17978


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


The remote host is affected by the vulnerability described in GLSA-200504-04 (mit-krb5: Multiple buffer overflows in telnet client)

A buffer overflow has been identified in the env_opt_add() function, where a response requiring excessive escaping can cause a heap-based buffer overflow. Another issue has been identified in the slc_add_reply() function, where a large number of SLC commands can overflow a fixed size buffer.
Impact :

Successful exploitation would require a vulnerable user to connect to an attacker-controlled telnet host, potentially executing arbitrary code with the permissions of the telnet user on the client.
Workaround :

There is no known workaround at this time.


All mit-krb5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/mit-krb5-1.3.6-r2'
