CVE-2026-71392
GNU Emacs for Android is vulnerable to an integer overflow in the sfntreadcmapformat12 function in src/sfnt.c. When processing a crafted TrueType font file, an unguarded addition in the xmalloc allocation call wraps around on 32-bit builds, causing a heap buffer overflow write. An attacker can...
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-2026-71394 Heap Use of Uninitialized Memory in GNU Emacs for Android
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-2026-71393
CVE-2026-71393 affects GNU Emacs for Android. A 32-bit font length value in sfnt_read_name_table() can overflow when computing the allocation size, causing an undersized heap allocation. A crafted TrueType font can trigger a read() past the buffer, leading to heap memory corruption and potential ...
CVE-2026-71393 Heap Buffer Overflow in GNU Emacs for Android
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...
