## Description

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.
