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.
