Multiple security issues were discovered in MediaWiki: SpecialUserRights could leak whether a user existed or not, multiple code paths lacked HTML sanitisation allowing for cross-site scripting and TOTP validation applied insufficient rate limiting against brute force attempts (CVE-2020-25812, CVE-2020-25813, CVE-2020-25814, CVE-2020-25815, CVE-2020-25827,
When Samba is used as a domain controller, an unauthenticated attacker on the network can gain administrator access by exploiting a netlogon protocol flaw (CVE-2020-1472). Note that Samba installations are not vulnerable unless they have the smb.conf
An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure (CVE-2020-24659).
AppCache manifest poisoning due to url encoded character processing (CVE-2020-12415). Use-after-free in WebRTC VideoBroadcaster (CVE-2020-12416).
Mozilla developer Jason Kratzer reported memory safety bugs present in Firefox ESR 78.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code (CVE-2020-15673).
The mount.cifs utility has a shell injection issue where one can embed shell commands via the username mount option. Those commands will be run via popen() in the context of the user calling mount (CVE-2020-14342). References:
An issue has been found in PowerDNS Authoritative Server before 4.3.1 where an authorized user with the ability to insert crafted records into a zone might be able to leak the content of uninitialized memory. Such a user could be a customer inserting data via a control panel, or somebody with access to the REST API. Crafted records cannot be inserted via AXFR (CVE-2020-17482).
An XSS vulnerability was discovered in noVNC before 0.6.2 in which the remote VNC server could inject arbitrary HTML into the noVNC web page via the messages propagated to the status field, such as the VNC server name. (CVE-2017-18635) References:
url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion. (CVE-2020-25219)
