Mandriva Linux Security Advisory : OpenEXR (MDVSA-2009:190)
High Nessus Plugin ID 40465
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple 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.
SolutionUpdate the affected packages.
