Gentoo Linux Security Advisory 201006-15 - Multiple integer overflow errors in XEmacs might allow remote, user-assisted attackers to execute arbitrary code. Tielei Wang reported multiple integer overflow vulnerabilities in the tiff_instantiate(), png_instantiate() and jpeg_instantiate() functions in glyphs-eimage.c, all possibly leading to heap-based buffer overflows. Versions less than 21.4.22-r1 are affected.
