Summary

Multiple integer overflows in glyphs-eimage.c in XEmacs 21.4.22, when running on Windows, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) the tiff_instantiate function processing a crafted TIFF file, (2) the png_instantiate function processing a crafted PNG file, and (3) the jpeg_instantiate function processing a crafted JPEG file, all which trigger a heap-based buffer overflow. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
