rdesktop: Remote code execution in rdpsnddbg_process

rdesktop versions up to and including v1.8.3 contain an Integer Underflow that leads to a Heap-Based Buffer Overflow in the function rdpsnddbg_process() and results in memory corruption and probably even a remote code execution.

rdesktop: Denial of Service in process_demand_active

rdesktop versions up to and including v1.8.3 contain an Out-Of-Bounds Read in the function process_demand_active() that results in a Denial of Service (segfault).

rdesktop: Memory corruption in rdp_in_unistr

rdesktop versions up to and including v1.8.3 contain an Integer Overflow that leads to a Heap-Based Buffer Overflow in the function rdp_in_unistr() and results in memory corruption and possibly even a remote code execution.

rdesktop: Denial of Service in mcs_recv_connect_response and mcs_parse_domain_params

rdesktop versions up to and including v1.8.3 contains several Integer Signedness errors that lead to Out-Of-Bounds Reads in the file mcs.c and result in a Denial of Service (segfault).

kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS

An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.

In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could modify new comments made by users with greater privileges, possibly causing XSS.

In WordPress before 4.9.9 and 5.x before 5.0.1, authors could bypass intended restrictions on post types via crafted input.

In WordPress before 4.9.9 and 5.x before 5.0.1, the user-activation page could be read by a search engine's web crawler if an unusual configuration were chosen. The search engine could then index and display a user's e-mail address and (rarely) the password that was generated by default.

In WordPress before 4.9.9 and 5.x before 5.0.1, crafted URLs could trigger XSS for certain use cases involving plugins.

In WordPress before 4.9.9 and 5.x before 5.0.1, when the Apache HTTP Server is used, authors could upload crafted files that bypass intended MIME type restrictions, leading to XSS, as demonstrated by a .jpg file without JPEG data.

In WordPress before 4.9.9 and 5.x before 5.0.1, contributors could conduct PHP object injection attacks via crafted metadata in a wp.getMediaItem XMLRPC call. This is caused by mishandling of serialized data at phar:// URLs in the wp_get_attachment_thumb_file function in wp-includes/post.php.

In WordPress before 4.9.9 and 5.x before 5.0.1, authors could modify metadata to bypass intended restrictions on deleting files.
