Description

The remote host is affected by the vulnerability described in GLSA-200807-14 (Linux Audit: Buffer overflow)

A stack-based buffer overflow has been reported in the
audit_log_user_command() function in the file lib/audit_logging.c when
processing overly long arguments.

Impact :

A local attacker could execute a specially crafted command on the host
running Linux Audit, possibly resulting in the execution of arbitrary
code with the privileges of the user running Linux Audit.

Workaround :

There is no known workaround at this time.
