- --------------------------------------------------------------------------
Package : libwmf
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.
