Description

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue.

Affected configurations

• capstone-engine capstone (< 6.0.0) • capstone-engine capstone 6.0.0
