Name of the Vulnerable Software and Affected Versions
XEmacs version 21.4.22
Description
The issue is related to multiple integer overflows in the glyphs-eimage.c file of XEmacs, specifically when running on Windows. These overflows can be triggered by processing crafted image files, including TIFF, PNG, and JPEG files, through the
tiff instantiate, png instantiate, and jpeg instantiate functions, respectively. This can lead to a denial of service (crash) or potentially allow remote attackers to execute arbitrary code due to a heap-based buffer overflow.Recommendations
For XEmacs version 21.4.22, consider avoiding the use of the
tiff instantiate, png instantiate, and jpeg instantiate functions until a patch is available, or restrict the processing of TIFF, PNG, and JPEG files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability. Encontrou algum problema na descrição? Tem algo a acrescentar?
