CVE-2022-29488

Code execution via uninitialized font pointer

Published Jun 1, 2022 · Updated Apr 16, 2025

Out-of-bounds read in Cscape Csfont before 9.90 SP5 allows context-dependent attackers to execute code through a crafted font file. When the Font Editor opens an untrusted .fnt file, Csfont dereferences an uninitialized pointer and reads beyond the intended buffer. User interaction is required, and execution occurs in the context of the Cscape process; the flaw is not remotely exploitable.
