The configure script in gnash 0.8.8 allows local users to overwrite arbitrary files via a symlink attack on the (1) /tmp/gnash-configure-errors.$$, (2) /tmp/gnash-configure-warnings.$$, or (3) /tmp/gnash-configure-recommended.$$ files.

Several vulnerabilities have been identified in Gnash, the GNU Flash player.

  - CVE-2012-1175     Tielei Wang from Georgia Tech Information Security     Center discovered a vulnerability in GNU Gnash which is     caused due to an integer overflow error and can be     exploited to cause a heap-based buffer overflow by     tricking a user into opening a specially crafted SWF     file.

  - CVE-2011-4328     Alexander Kurtz discovered an unsafe management of HTTP     cookies. Cookie files are stored under /tmp and have     predictable names, and the vulnerability allows a local     attacker to overwrite arbitrary files the users has     write permissions for, and are also world-readable which     may cause information leak.

  - CVE-2010-4337     Jakub Wilk discovered an unsafe management of temporary     files during the build process. Files are stored under     /tmp and have predictable names, and the vulnerability     allows a local attacker to overwrite arbitrary files the     users has write permissions for.
