The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200507-11
(MIT Kerberos 5: Multiple vulnerabilities)
Daniel Wachdorf discovered that MIT Kerberos 5 could corrupt the
heap by freeing unallocated memory when receiving a special TCP request
(CAN-2005-1174). He also discovered that the same request could lead to
a single-byte heap overflow (CAN-2005-1175). Magnus Hagander discovered
that krb5_recvauth() function of MIT Kerberos 5 might try to
double-free memory (CAN-2005-1689).
Although exploitation is considered difficult, a remote attacker
could exploit the single-byte heap overflow and the double-free
vulnerability to execute arbitrary code, which could lead to the
compromise of the whole Kerberos realm. A remote attacker could also
use the heap corruption to cause a Denial of Service.
There are no known workarounds at this time.
