Description:

The remote host is affected by the vulnerability described in GLSA-200410-08
(ncompress: Buffer overflow)


compress and uncompress do not properly check bounds on command line
options, including the filename. Large parameters would trigger a buffer
overflow.

Impact

By supplying a carefully crafted filename or other option, an attacker
could execute arbitrary code on the system. A local attacker could only
execute code with his own rights, but since compress and uncompress are
called by various daemon programs, this might also allow a remote attacker
to execute code with the rights of the daemon making use of ncompress.

Workaround

There is no known workaround at this time.

Solution:
All ncompress users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=app-arch/ncompress-4.2.4-r1"
# emerge ">=app-arch/ncompress-4.2.4-r1"


Risk factor : Medium
