The URI handlers in Konqueror for KDE 3.2.2 and earlier do not properly filter "-" characters that begin a hostname in a 1 telnet, 2 rlogin, 3 ssh, or 4 mailto URI, which allows remote attackers to manipulate the options that are passed to the associated programs, possibly to read arbitrary files...

SUSE CVE-2022-42915

curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTPS URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request HTTP...
