Debian: New libwmf packages fix denial of service

Tavis Ormandy discovered that the embedded GD library copy in libwmf, a library to parse windows metafiles (WMF), makes use of a pointer after it was already freed. An attacker using a crafted WMF file can cause a denial of service or possibly the execute arbitrary code via applications using this library. Updated packages are available from security.debian.org.

Vulnerability  : pointer use-after-free
Problem type   : local (remote)
Debian-specific: no
Debian bug     : 526434
CVE ID         : CVE-2009-1364


Tavis Ormandy discovered that the embedded GD library copy in libwmf,
a library to parse windows metafiles (WMF), makes use of a pointer
after it was already freed.  An attacker using a crafted WMF file can
cause a denial of service or possibly the execute arbitrary code via
applications using this library.


For the oldstable distribution (etch), this problem has been fixed in
version 0.2.8.4-2+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 0.2.8.4-6+lenny1.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 0.2.8.4-6.1.


We recommend that you upgrade your libwmf packages.
