NixOS vulnerability analysis and mitigation
Overview
SWFMill commit 53d7690 was discovered to contain a heap-buffer overflow vulnerability via _interceptorstrlen.part at /sanitizercommon/sanitizercommon_interceptors.inc. The vulnerability was identified and reported on July 11, 2022 (GitHub Issue).
Technical details
The heap-buffer overflow occurs in the getString() function within SWF::Reader when processing SWF files. The vulnerability is triggered during the parsing of SWF files when converting them to XML format using the swf2xml command. The issue specifically manifests in the _interceptorstrlen.part.36 function, where a READ operation of size 1 occurs at an out-of-bounds memory address. The overflow happens 1 byte to the right of a 20466-byte allocated region (GitHub Issue).
Impact
When exploited, this vulnerability can lead to a program crash, resulting in a denial of service condition. The heap-buffer overflow could potentially allow for memory corruption, which might enable arbitrary code execution in certain circumstances (GitHub Issue).
