CVE-2026-71391

A flaw was found in GNU Emacs, specifically in GNU Emacs for Android. An off-by-one error can occur when a specially crafted font file is processed due to an improper bounds check. This can cause a heap-based buffer over-read, exposing heap memory contents. Mitigation Do not load untrusted font...

DEBIAN-CVE-2026-71391

GNU Emacs for Android contains an off-by-one error in the gvar table parser in src/sfnt.c. The shared-coordinate index boundary check in sfntvarysimpleglyph and sfntvarycompoundglyph uses a strict greater-than comparison instead of greater-than-or-equal, allowing a crafted TrueType variable font ...

UBUNTU-CVE-2026-71394

GNU Emacs for Android improperly validates the table header input in sfntreadtabledirectory in src/sfnt.c. Due to an incorrect comparison variable in the read-length check, a crafted font file that claims to contain more table directory entries than actually present causes the parser to return a...

UBUNTU-CVE-2026-71393

GNU Emacs for Android is vulnerable to an integer overflow in sfntreadnametable in src/sfnt.c. The function computes an allocation size using a 32-bit length value from a TrueType font file without overflow checking. On 32-bit targets, a crafted font causes the calculation to wrap, resulting in a...
