The remote Gentoo host is missing one or more security-related
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.
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.
There is no known workaround at this time.
