[ MDVSA-2009:190 ] OpenEXR

[dude67]

_______________________________________________________________________

Package : OpenEXR
Date : August 2, 2009
Affected: 2008.1, 2009.0, 2009.1, Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in OpenEXR:

Multiple integer overflows in OpenEXR 1.2.2 and 1.6.1
allow context-dependent attackers to cause a denial of service
(application crash) or possibly execute arbitrary code via unspecified
vectors that trigger heap-based buffer overflows, related to (1)
the Imf::PreviewImage::PreviewImage function and (2) compressor
constructors. NOTE: some of these details are obtained from third
party information (CVE-2009-1720).

The decompression implementation in the Imf::hufUncompress function in
OpenEXR 1.2.2 and 1.6.1 allows context-dependent attackers to cause a
denial of service (application crash) or possibly execute arbitrary
code via vectors that trigger a free of an uninitialized pointer
(CVE-2009-1721).

This update provides fixes for these vulnerabilities.
