CVE-2017-2813
HighSummary
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.
Risk Assessment
Exploitation of this vulnerability could lead to remote code execution, posing a significant security risk to organizational systems.
Recommendation
It is recommended to update IrfanView to the latest version to mitigate this vulnerability and to restrict opening unknown jpeg2000 files.

See all- CVE-2026-121517Medium
A vulnerability was detected in IrfanView 4.76.0.0 on Win64 in an unknown functionality of the TIFF Wang Annotation Handler component, resulting in a heap-based buffer overflow. The attack is possible remotely, though of high complexity and difficult to exploit; the exploit is now public. The vendor confirms that the TIF-Annotations option is OFF by default, so normal users are not affected, and rates the danger level as low.
- CVE-2021-46064High
IrfanView 4.59 is vulnerable to a buffer overflow in the function at address 0x413c70 (in the 32-bit version). The vulnerability is triggered when the user opens a malicious TIFF image.
- CVE-2020-23546High
IrfanView 4.54 contains a vulnerability that allows an attacker to cause a denial of service or possibly other unspecified impacts via a crafted XBM file. The issue is related to data from a faulting address being used as arguments in a function call in FORMATS!ReadMosaic.
Original NVD description (English source)
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.
