DESCRIPTION:
A vulnerability has been reported in Yelp, which potentially can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a format string error when
reporting an invalid URI to the user. This can be exploited by
tricking the user into e.g. opening a specially crafted URI
containing format string specifiers.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in version 2.23.1. Other versions may
also be affected.

Do not open untrusted links using Yelp.

Fixed in the SVN repository.
