  SUMMARY   XnView Formats PlugIn is prone to an overflow condition. The JLS Plugin (xjpegls.dll) library fails to properly sanitize user-supplied input resulting in a heap-based buffer overflow. With a specially crafted JLS compressed image file, a context-dependent attacker could potentially execute arbitrary code.   POC file posted at: http://www.reactionpenetrationtesting.co.uk/vuln.jls https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/21741.jls   CVE number: CVE-2012-4988 Impact: High Vendor homepage: http://www.xnview.com/ Vendor notified: 29/06/2012 Vendor response: Fix was promised for 1.99.1 but no fix was released Found by: Joseph Sheridan, Director of Reaction Information Security ABOUT REACTIONIS   Reaction Information Security is a leading independent pen test consultancy specialising in delivering the highest quality services including network pen testing and web application security testing.
