GLSA-200701-21 : MIT Kerberos 5: Arbitrary Remote Code Execution
High Nessus Plugin ID 24257
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200701-21 (MIT Kerberos 5: Arbitrary Remote Code Execution)
The Kerberos administration daemon, and possibly other applications using the GSS-API or RPC libraries, could potentially call a function pointer in a freed heap buffer, or attempt to free an uninitialized pointer.
A remote attacker may be able to crash an affected application, or potentially execute arbitrary code with root privileges.
There is no known workaround at this time.
SolutionAll MIT Kerberos 5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/mit-krb5-1.5.2'
