libpano13: Format string vulnerability

Background

libpano13 is Helmut Dersch’s panorama toolbox library.

Description

A format string issue exists within panoFileOutputNamesCreate() where unvalidated input is passed directly into the formatter.

Impact

A remote attacker could entice a user to open a specially crafted file using libpano13, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All libpano13 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/libpano13-2.9.20"
