A flaw was found in libsoup. This is a stack-based buffer overflow vulnerability that occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this vulnerability by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may cause application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction.
