Package : gnash
Vulnerability : several
Problem type : local / local (remote)
Debian-specific: no
CVE ID : CVE-2010-4337 CVE-2011-4328 CVE-2012-1175
Debian Bug : 605419 649384 664023

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, vulnerability
that 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,
vulnerability that allows a local attacker to overwrite arbitrary files
the users has write permissions for.

For the stable distribution (squeeze), this problem has been fixed in
version 0.8.8-5+squeeze1.

For the unstable distribution (sid), this problem has been fixed in
version 0.8.10-5.

previously freed memory if an upstream server returned a specially crafted HTTP
response, potentially exposing sensitive information.

For the stable distribution (squeeze), this problem has been fixed in
version 0.7.67-3+squeeze2.

For the unstable distribution (sid), this problem has been fixed in
version 1.1.17-1.

We recommend that you upgrade your nginx packages.
