Overview

Affected versions of this package are vulnerable to Out-of-bounds Write in the start_decoder function, an attacker can execute arbitrary code by exploiting an integer overflow that leads to memory write past an allocated heap buffer. This is due to the potential integer overflow in sizeof(char*) * (f->comment_list_length) which may cause setup_malloc to allocate less memory than required. Additionally, another integer overflow can be exploited to force setup_malloc to return 0, making the exploit more reliable.
