GLSA-200410-08 : ncompress: Buffer overflow
High Nessus Plugin ID 15446
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
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.
There is no known workaround at this time.
SolutionAll 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'
