A flaw was found in the soup_multipart_new_from_message() function of thelibsoup HTTP library, which is commonly used by GNOME and otherapplications to handle web communications. The issue occurs when thelibrary processes specially crafted multipart messages. Due to impropervalidation, an internal calculation can go wrong, leading to an integerunderflow. This can cause the program to access invalid memory and crash.As a result, any application or server using libsoup could be forced toexit unexpectedly, creating a denial-of-service (DoS) risk.
