Overview
IrfanView DXF File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability (CVE-2024-11549) was discovered and disclosed on November 21, 2024. This vulnerability affects IrfanView installations and specifically exists within the parsing of DXF files. The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) (NVD, ZDI Advisory).
Technical details
The vulnerability stems from the lack of proper validation of user-supplied data during DXF file parsing, which can result in a write past the end of an allocated buffer (CWE-787: Out-of-bounds Write).

Impact
If successfully exploited, this vulnerability allows attackers to execute arbitrary code in the context of the current process, potentially leading to complete system compromise with the privileges of the affected process (ZDI Advisory).
Mitigation and workarounds
The vulnerability has been fixed in IrfanView version 4.70 with plugins version 4.70. Users are advised to upgrade to this version to protect against potential exploitation (ZDI Advisory).
