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."
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
