CVE Informations

Related Weaknesses

CWE-ID	Weakness Name	Source
CWE-119	Improper Restriction of Operations within the Bounds of a Memory Buffer The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

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. As a CESG CHECK Service Provider we are authorised to carry out penetration testing on classified government networks. AFFECTED PRODUCTS XnView 1.99 and 1.99.1, 'All Plugins 1.90' and Xjpegls.dll (version 1.96.0.0) previous versions may also be affected. DETAILS 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. IMPACT If a user could be enticed to open a malicious JLS file, the attack could result in remote code execution. SOLUTION No solution at the time of writing. Never open files from untrusted sources.
