CVSS: 9.8EPSS: 0%CPEs: 21EXPL: 0CVE-2017-18922 – libvncserver: websocket decoding buffer overflow
https://notcve.org/view.php?id=CVE-2017-18922
It was discovered that websockets.c in LibVNCServer prior to 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, causing a heap-based buffer overflow. Se detectó que el archivo websockets.c en LibVNCServer versiones anteriores a 0.9.12, no decodificaba apropiadamente determinados tramas de WebSocket. Un atacante malicioso podría explotar esto mediante el envío de tramas de WebSocket especialmente diseñadas hacia un servidor, causando un desbordamiento del búfer en la región heap de la memoria A flaw was found in libvncserver. A heap-based buffer overflow within the websocket decoding functionality is possible, which can lead to exploitation by a malicious attacker to overwrite a function pointer. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00066.html http://www.openwall.com/lists/oss-security/2020/06/30/3 https://bugzilla.redhat.com/show_bug.cgi?id=1852356 https://cer • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 0CVE-2020-4067 – Improper Initialization in coturn
https://notcve.org/view.php?id=CVE-2020-4067
In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client. This has been fixed in 4.5.1.3. En coturn anterior a la versión 4.5.1.3, se presenta un problema por el cual el búfer de respuesta STUN/TURN no se inicializa apropiadamente. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00010.html https://github.com/coturn/coturn/blob/aab60340b201d55c007bcdc853230f47aa2dfdf1/ChangeLog#L15 https://github.com/coturn/coturn/issues/583 https://github.com/coturn/coturn/security/advisories/GHSA-c8r8-8vp5-6gcm https://lists.debian.org/debian-lts-announce/2020/07/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5G35UBNSRLL6SYRTODYTMBJ65TLQILUM https://lists.fedoraproject.org/archives/list/p • CWE-665: Improper Initialization •
