CyberRota Analysis
AI-GeneratedThe vulnerability affects the nothings stb TrueType library, specifically in the stbtt__GetGlyphShapeTT() function used for parsing TrueType font files. An attacker can exploit this flaw by crafting a malformed TTF file, leading to a heap-buffer overflow that may result in application crashes or arbitrary code execution. Developers of applications utilizing this library, particularly in game engines or graphics software, should prioritize patching to mitigate potential exploitation risks.

Original NVD Description
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 stbtt__GetGlyphShapeTT() function within the nothings stb_truetype.h library when parsing malformed TTF (TrueType Font) files. The vulnerability resides in the glyph data parsing path. An attacker can craft a malformed TTF file with an inflated endPtsOfContours value and truncate the remaining glyph data. When an application utilizing stb_truetype.h (such as various game engines or graphics software) attempts to load, bake, or render this malformed font via stbtt_GetGlyphShape(), the parser will attempt to read past the end of the glyph data buffer, triggering the out-of-bounds read.
