CVE-2024-11560: 
IrfanView vulnerability analysis and mitigation

IrfanView DXF File Parsing Memory Corruption Remote Code Execution Vulnerability (CVE-2024-11560) was discovered and disclosed on November 21, 2024. This vulnerability affects IrfanView installations and requires user interaction to exploit, specifically when opening malicious DXF files. The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) (NVD, ZDI Advisory).

The vulnerability exists within the parsing of DXF files in IrfanView. The specific issue stems from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. This has been classified as an Out-of-bounds Write (CWE-787) vulnerability. The CVSS v3.1 vector string is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, no privileges required, and user interaction required (ZDI Advisory).

If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process. This means an attacker could potentially gain the same privileges as the application running the vulnerable code, leading to complete compromise of the affected system (ZDI Advisory).

The vulnerability has been fixed in IrfanView version 4.70 with plugins version 4.70. Users are advised to upgrade to this version to mitigate the risk (ZDI Advisory).
