IrfanView version 4.44 (32bit) might allow attackers to cause a denial of service or possibly have unspecified other impact via a crafted .rle file, related to "Data from Faulting Address controls Branch Selection starting at ntdll_77df0000!RtlpFreeHeap+0x00000000000003ca."
An exploitable integer overflow vulnerability exists in the JPEG 2000 parser functionality of IrfanView 4.44. A specially crafted jpeg2000 image can cause an integer overflow leading to wrong memory allocation resulting in arbitrary code execution. Vulnerability can be triggered by viewing the image in via the application or by using thumbnailing feature of IrfanView.
Buffer overflow in IrfanView before 4.37, when a multibyte-character directory name is used, allows user-assisted remote attackers to execute arbitrary code via a crafted file that is incorrectly handled by the Thumbnail tooltips feature in the Thumbnails window.
Heap-based buffer overflow in IrfanView before 4.33 allows remote attackers to execute arbitrary code via a crafted RLE compressed bitmap file such as a DIB, RLE, or BMP image.
Heap-based buffer overflow in IrfanView before 4.32 allows remote attackers to execute arbitrary code via crafted "Rows Per Strip" and "Samples Per Pixel" values in a TIFF image file.
Heap-based buffer overflow in jpeg_ls.dll in the Jpeg_LS (aka JLS) plugin in the formats plugins in IrfanView PlugIns before 4.34 allows remote attackers to execute arbitrary code via a crafted JLS file.
Heap-based buffer overflow in the FlashPix PlugIn before 4.3.4.0 for IrfanView might allow remote attackers to execute arbitrary code via a .fpx file containing a crafted FlashPix image that is not properly handled during decompression.
Stack-based buffer overflow in the JPEG2000 plugin in IrfanView PlugIns before 4.33 allows remote attackers to execute arbitrary code via a JPEG2000 (JP2) file with a crafted Quantization Default (QCD) marker segment.
