CVE-2024-11508: 
IrfanView vulnerability analysis and mitigation

CVE-2024-11508 is a type confusion vulnerability discovered in IrfanView that affects version 4.62 and potentially earlier versions. The vulnerability was disclosed on November 22, 2024, and was assigned a CVSS v3.1 base score of 7.8 (HIGH). This security flaw specifically impacts the DXF file parsing functionality in IrfanView (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 type confusion condition. The vulnerability has been assigned a CVSS v3.1 vector of CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating a high severity level with local access vector, low attack complexity, no privileges required, and user interaction required (NVD).

If successfully exploited, this vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView. The execution would occur in the context of the current process, potentially leading to complete system compromise with the same privileges as the application (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).
