Title: CamlImages Image Parsing Multiple Heap Overflow Vulnerabilities
Severity: CRITICAL
Description:
CamlImages is an open-source library for processing images.
CamlImages is prone to multiple heap-overflow vulnerabilities because it fails to properly validate user-supplied data when parsing GIF and JPEG images. Specifically, these issues arise in the 'gifread.c' and 'jpegread.c' source files, which contain functions that fail to properly validate the width and height of an image.
An attacker may exploit these issues by enticing victims into processing specially crafted images.
Successful exploits may allow the attacker to execute arbitrary code in the context of applications that use the affected library. Failed exploit attempts will likely result in denial-of-service conditions.
CamlImages 2.2 is vulnerable; other versions may also be affected.
