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-2026-71392

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-2026-71391

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 ...

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-2026-71392 Integer Overflow in GNU Emacs for Android

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-2026-71391

GNU Emacs for Android is affected by an off-by-one in the gvar table parser (src/sfnt.c). The shared-coordinate index boundary check in sfnt_vary_simple_glyph() and sfnt_vary_compound_glyph() uses a > comparison instead of >=, allowing a crafted TrueType variable font to bypass the check an...

EUVD-2026-54489

A heap-buffer-overflow vulnerability exists in the nothings stb TrueType library, up to version 1.26, that is used for parsing TrueType font files. The vulnerability exists in the stbttGetGlyphShapeTT function within the nothings stbtruetype.h library when parsing malformed TTF TrueType Font file...

CVE-2026-18497

The CVE-2026-18497 issue affects the nothings stb TrueType library (stb_truetype.h) up to v1.26. The vulnerability lies in stbtt__GetGlyphShapeTT() when parsing malformed TrueType fonts; an inflated endPtsOfContours value can cause the parser to read past the glyph data buffer, triggering a heap-...

libXfont2: BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow

A flaw was found in libXfont2. In the BitmapScaleBitmaps function, an integer overflow can occur when calculating the memory needed for font glyphs. This overflow leads to a heap buffer overflow, where a smaller-than-required memory buffer is allocated. A local attacker can exploit this by loadin...

python-pillow: Pillow: Denial of Service via excessive memory allocation when processing font files

A flaw was found in Pillow, a Python imaging library. When processing a specially crafted font file, the library's font compilation function does not adequately check for excessive memory allocation. This oversight allows a remote attacker to trigger an unreasonable consumption of system memory,...
