[GLSA-200409-13] LHa: Multiple vulnerabilities

Vulnerability Assessment Summary
LHa: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200409-13
(LHa: Multiple vulnerabilities)

The command line argument as well as the archive parsing code of LHa lack
sufficient bounds checking. Furthermore, a shell meta character command
execution vulnerability exists in LHa, since it does no proper filtering on
directory names.

Impact

Using a specially crafted command line argument or archive, a possible hacker can
cause a buffer overflow and could possibly run arbitrary code. The shell
meta character command execution could lead to the execution of arbitrary
commands by a possible hacker using directories containing shell meta characters
in their names.

Workaround

There is no known workaround at this time.
