Synopsis :

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

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'
