Description
A flaw was found in libsoup. An unsigned integer underflow in the soup_filter_input_stream_read_until() function causes a heap buffer over-read when parsing multipart HTTP responses. A malicious HTTP server can exploit this by sending a crafted multipart response, potentially causing the client application to crash or disclose sensitive heap memory.
Affected configurations
• gnome libsoup
• redhat enterprise linux 6.0
• redhat enterprise linux 7.0
• redhat enterprise linux 8.0
• redhat enterprise linux 9.0
