Name of the Vulnerable Software and Affected Versions stb image.h version 2.27

Description The issue is related to a heap-based buffer overflow in the stbi jpeg load function of the stb image.h library, which can lead to Information Disclosure or Denial of Service. This can be exploited by a remote attacker to gain access to confidential data or cause a service disruption.

Recommendations For stb image.h version 2.27, consider updating to a newer version that addresses the heap-based buffer overflow issue in the stbi jpeg load function. As a temporary workaround, consider restricting the use of the stbi jpeg load function to minimize the risk of exploitation.
