Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200611-24
(LHa: Multiple vulnerabilities)

Tavis Ormandy of the Google Security Team discovered several
vulnerabilities in the LZH decompression component used by LHa. The
make_table function of unlzh.c contains an array index error and a
buffer overflow vulnerability. The build_tree function of unpack.c
contains a buffer underflow vulnerability. Additionally, unlzh.c
contains a code that could run in an infinite loop.

Impact :

By enticing a user to uncompress a specially crafted archive, a remote
attacker could cause a Denial of Service by CPU consumption or execute
arbitrary code with the rights of the user running the application.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=app-arch/lha-114i-r6'

Risk factor :

High / CVSS Base Score : 7.5
