[GLSA-200410-08] ncompress: Buffer overflow Vulnerability Scan
Vulnerability Scan Summary
ncompress: Buffer overflow
Detailed Explanation for this Vulnerability Test
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, a possible hacker
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"
Threat Level: Medium
