Doc Text:
A flaw was found in LERC. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by submitting specially crafted image data to an application using the library. Processing the malicious input triggers an integer overflow that leads to an out-of-bounds memory write, causing the application to crash.

Description OSIDB Bzimport 2026-09-25 21:01:19 UTC 
Esri LERC is an open-source image or raster format which supports rapid encoding and decoding for any pixel type. A Heap based Out-of-Bounds Write via Integer Overflow in LERC versions 4.1.0 and earlier may allow a remote, unauthenticated attacker who can pass specifically crafted attacker controlled imagery to an application that uses LERC to crash the application, leading to a denial of service.
