Description

The remote host is affected by the vulnerability described in GLSA-200809-01 (yelp: User-assisted execution of arbitrary code)

Aaron Grattafiori reported a format string vulnerability in the     window_error() function in yelp-window.c.

Impact :

A remote attacker can entice a user to open specially crafted 'man:' or     'ghelp:' URIs in yelp, or an application using yelp such as Firefox or     Evolution, and execute arbitrary code with the privileges of that user.

Workaround :

There is no known workaround at this time.
