libxfont2: Font Server Client encoding[] Out-Of-Bounds Read/Write

A flaw was found in the libXfont2 font-server client. A remote attacker, by operating a malicious font server, could exploit an out-of-bounds read/write vulnerability. This occurs because the client incorrectly handles font data, leading to an out-of-bounds memory access. This can lead to privile...

SUSE 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...

SUSE 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...

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...

CVE-2026-71393
