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.
