https://notcve.org/view.php?id=CVE-2020-14345
A flaw was found in X.Org Server before xorg-x11-server 1.20.9. An Out-Of-Bounds access in XkbSetNames function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en X.Org Server versiones anteriores a xorg-x11-server 1.20.9. Un acceso fuera de límites en la función XkbSetNames puede conllevar a una vulnerabilidad de escalada de privilegios. • http://www.openwall.com/lists/oss-security/2021/01/15/1 https://bugzilla.redhat.com/show_bug.cgi?id=1862241 https://lists.x.org/archives/xorg-announce/2020-August/003058.html https://security.gentoo.org/glsa/202012-01 https://usn.ubuntu.com/4488-2 https://usn.ubuntu.com/4490-1 https://www.zerodayinitiative.com/advisories/ZDI-20-1416 https://access.redhat.com/security/cve/CVE-2020-14345 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2020-24659 – gnutls: Heap buffer overflow in handshake with no_renegotiation alert sent
https://notcve.org/view.php?id=CVE-2020-24659
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. Se detectó un problema en GnuTLS versiones anteriores a 3.6.15. Un servidor puede desencadenar una desreferencia del puntero NULL en un cliente TLS versión 1.3, si una alerta no_renegotiation es enviada con una sincronización no prevista y luego se produce un segundo protocolo de enlace no válido. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00060.html https://gitlab.com/gnutls/gnutls/-/issues/1071 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/62BUAI4FQQLG6VTKRT7SUZPGJJ4NASQ3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AWN56FDLQQXT2D2YHNI4TYH432TDMQ7N https://security.gentoo.org/glsa/202009-01 https://security.netapp.com/adviso • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference CWE-787: Out-of-bounds Write •
