Vulnerability from fkie_nvd - Published: 2025-07-30 20:15 - Updated: 2025-07-31 18:42
Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
ImageSharp is a 2D graphics library. In versions below 2.1.11 and 3.0.0 through 3.1.10, a specially crafted GIF file containing a malformed comment extension block (with a missing block terminator) can cause the ImageSharp GIF decoder to enter an infinite loop while attempting to skip the block. This leads to a denial of service. Applications processing untrusted GIF input should upgrade to a patched version. This issue is fixed in versions 2.1.11 and 3.1.11.

En versiones anteriores a la 2.1.11 y de la 3.0.0 a la 3.1.10, un archivo GIF especialmente manipulado que contiene un bloque de extensi\u00f3n de comentario mal formado (sin un terminador de bloque) puede provocar que el decodificador GIF de ImageSharp entre en un bucle infinito al intentar omitir el bloque. Esto provoca una denegaci\u00f3n de servicio. Las aplicaciones que procesan entradas GIF no confiables deben actualizarse a una versi\u00f3n parcheada. Este problema est\u00e1 corregido en las versiones 2.1.11 y 3.1.11."
