fl0 fl0w has discovered a vulnerability in Jasc Paint Shop Pro, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the processing of PNG files. This can be exploited to cause a stack-based buffer overflow when a PNG file with e.g. a specially crafted "pHYs" chunk is opened.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 8.10. Other versions may also be affected.
Solution: Do not open files from untrusted sources.
