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

high Nessus Plugin ID 17978

Synopsis

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

Description

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.

Solution

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