XnSoft XnView Classic RWZ File Parsing Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of XnSoft XnView Classic. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of RWZ files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22913.

Buffer Overflow vulnerability in XnView Classic v.2.51.5 allows a local attacker to execute arbitrary code via a crafted TIF file.

Buffer Overflow vulnerability in XNView before 2.50, allows local attackers to execute arbitrary code via crafted GEM bitmap file.

Buffer Overflow vulnerability in XNView version 2.49.3, allows local attackers to execute arbitrary code via crafted TIFF file.

xnview.exe in XnView before 2.13 does not properly handle RLE strip lengths during processing of RGB files, which allows remote attackers to execute arbitrary code via the RLE strip size field in a RGB file, which leads to an unexpected sign extension error and a heap-based buffer overflow.

Heap-based buffer overflow in xnview.exe in XnView before 2.13 allows remote attackers to execute arbitrary code via the biBitCount field in a BMP file.

Heap-based buffer overflow in xnview.exe in XnView before 2.03 allows remote attackers to execute arbitrary code via a crafted RLE compressed layer in an XCF file.
