Buffer overflow in IrfanView 3.99 allows remote attackers to execute arbitrary code via a crafted animated cursor (ANI) file.

Buffer overflow in IrfanView 3.99 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via the (1) xoffset or (2) yoffset RLE command, or (3) large non-RLE encoded blocks in a crafted BMP image, as demonstrated by rle8of3.bmp and rle8of4.bmp.

Stack-based buffer overflow in IrfanView 3.99 and 4.00 allows user-assisted remote attackers to execute arbitrary code via a crafted palette (.pal) file.

Heap-based buffer overflow in IrfanView before 4.27 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PSD image with RLE compression.

IrfanView before 4.27 does not properly handle an unspecified integer variable during processing of PSD images, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image file that triggers a heap-based buffer overflow, related to a "sign-extension error."

IrfanView 3.99 allows remote attackers to cause a denial of service (application crash) via a malformed WMF file.
