Description

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

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.
