Descriptions
A vulnerability was found in the libsoup package. This flaw stems from its failure to correctly verify the termination of multipart HTTP messages. This can allow a remote attacker to send a specially crafted multipart HTTP body, causing the libsoup-consuming server to read beyond its allocated memory boundaries (out-of-bounds read).
This update for libsoup fixes the following issues. Fixed off-by-one out-of-bounds read may lead to infoleak. Fixed integer underflow in soup_multipart_new_from_message leading to denial of service. Fixed NULL pointer dereference may lead to denial of service.
