Summary
Leptonica linked library version 1.79.0 contains a flaw that allows attackers to trigger an arithmetic exception via a crafted JPEG file. This results in a Denial of Service (DoS) of the application using the library.
Risk Assessment
An attacker can remotely crash or hang a service that processes JPEG images, disrupting system availability. The risk affects any application using the vulnerable Leptonica version to process untrusted image files.
Recommendation
Upgrade Leptonica to a version newer than 1.79.0 or apply the vendor patch. Until then, consider validating and restricting the processing of untrusted JPEG files.
