Vulnerabilities 8
-
Critical 9.0
Libsoup: double free on soup_message_headers_get_content_disposition() through "soup-message-headers.c" via "params" ghashtable value
A use-after-free type vulnerability was found in libsoup, in the soup_message_headers_get_content_disposition() function. This flaw allows a malicious HTTP client to cause memory corruption in the libsoup server.
-
High 7.5
Libsoup: out of bounds reads in soup_headers_parse_request()
A flaw was found in libsoup, where the soup_headers_parse_request() function may be vulnerable to an out-of-bound read. This flaw allows a malicious user to use a specially crafted HTTP request to crash the HTTP server.
-
High 7.5
Libsoup: null pointer dereference in soup_message_headers_get_content_disposition when "filename" parameter is present, but has no value in content-disposition header
A flaw was found in libsoup, where the soup_message_headers_get_content_disposition() function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function.
-
Medium 6.8
Libsoup: information disclosure may leads libsoup client sends authorization header to a different host when being redirected by a server
A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued …
-
Medium 6.5
Libsoup: heap buffer overflow in sniff_unknown()
A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over-read.
-
Medium 6.5
Libsoup: heap buffer overflows in sniff_feed_or_html() and skip_insignificant_space()
A flaw was found in libsoup. A vulnerability in sniff_feed_or_html() and skip_insignificant_space() functions may lead to a heap buffer over-read.
-
Medium 6.5
Libsoup: memory leak on soup_header_parse_quality_list() via soup-headers.c
A flaw was found in libsoup. It is vulnerable to memory leaks in the soup_header_parse_quality_list() function when parsing a quality list that contains elements with all zeroes.
-
Medium 5.9
Libsoup: integer overflow in append_param_quoted
A flaw was found in libsoup. The libsoup append_param_quoted() function may contain an overflow bug resulting in a buffer under-read.
