A heap-use-after-free flaw was found in ImageSharp's InitializeImage() function of PngDecoderCore.cs file. This vulnerability is triggered when an attacker passes a specially crafted PNG image file to ImageSharp for conversion, potentially leading to information disclosure.
Patches
The problem has been patched. All users are advised to upgrade to v3.1.3 or v2.1.7.
A vulnerability discovered in the ImageSharp library, where the processing of specially crafted files can lead to excessive memory usage in image decoders. The vulnerability is triggered when ImageSharp attempts to process image files that are designed to exploit this flaw.
This flaw can be exploited to cause a denial of service (DoS) by depleting process memory, thereby affecting applications and services that rely on ImageSharp for image processing tasks. Users and administrators are advised to update to the latest version of ImageSharp that addresses this vulnerability to mitigate the risk of exploitation.
Patches
The problem has been patched. All users are advised to upgrade to v3.1.4 or v2.1.8.
Workarounds
Before calling Image.Decode(Async), use Image.Identify to determine the image dimensions in order to enforce a limit.
A data leakage flaw was found in ImageSharp's JPEG and TGA decoders. This vulnerability is triggered when an attacker passes a specially crafted JPEG or TGA image file to a software using ImageSharp, potentially disclosing sensitive information from other parts of the software in the resulting image buffer.
Patches
The problem has been patched. All users are advised to upgrade to v3.1.4 or v2.1.8.
An Out-of-bounds Write vulnerability has been found in the ImageSharp gif decoder, allowing attackers to cause a crash using a specially crafted gif. This can potentially lead to denial of service.
Patches
The problem has been patched. All users are advised to upgrade to v3.1.5 or v2.1.9.
