CVE-2026-79515 Details
Description
An out-of-bounds read in the stbtt_GetGlyphShape component of nothings stb commit 31c1ad3 allows attackers to cause a Denial of Service (DoS) via sending a crafted TTF file.
A vulnerability allowing for an out-of-bounds read has been identified in the glyph shape parsing component of nothings stb, specifically in commit 31c1ad3. This issue arises when a crafted TrueType font (TTF) file is processed, leading to a denial-of-service condition. The root cause is an off-curve point at the end of a contour, which causes the parser to read beyond the allocated memory for vertex data.
