Lifecycle Timeline
4Description
A vulnerability was found in Nothings stb up to 1.26. Impacted is the function stbtt_InitFont_internal in the library stb_truetype.h of the component TTF File Handler. Performing a manipulation results in out-of-bounds read. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
Analysis
Out-of-bounds read in Nothings stb library up to version 1.26 allows remote attackers to trigger information disclosure via a crafted TTF file processed by the stbtt_InitFont_internal function in stb_truetype.h. Exploitation requires user interaction (opening a malicious font file) and publicly available exploit code exists; however, the vendor has not responded to early disclosure notification.
