What is CVE-2022-35081?

A heap-buffer overflow vulnerability exists in SWFTools that could be triggered by processing specially crafted PNG files. Specifically, the issue is caused by inadequate memory validation in the png_read_header function within the src/png2swf.c source file. This flaw can lead to potential memory corruption, allowing attackers to execute arbitrary code or cause a denial-of-service condition by manipulating the input data. Users of vulnerable SWFTools versions need to address this issue promptly to mitigate risks associated with malicious PNG files.
