CVE-2020-9383 – kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c
https://notcve.org/view.php?id=CVE-2020-9383
An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. Se detectó un problema en el kernel de Linux versión 3.16 hasta la versión 5.5.6. La función set_fdc en el archivo drivers/block/floppy.c, conlleva a una lectura fuera de límites de wait_til_ready porque el índice FDC no es comprobado para errores antes de asignarlos, también se conoce como CID-2e90ca68b0d2 An out-of-bounds (OOB) memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00039.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f9ac30a54dc0181ddac3705cdcf4775d863c530 https://github.com/torvalds/linux/commit/2e90ca68b0d2f5548804f22f0dd61145516171e3 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap& • CWE-125: Out-of-bounds Read •
CVE-2020-8794 – OpenSMTPD - OOB Read Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2020-8794
OpenSMTPD before 6.6.4 allows remote code execution because of an out-of-bounds read in mta_io in mta_session.c for multi-line replies. Although this vulnerability affects the client side of OpenSMTPD, it is possible to attack a server because the server code launches the client code during bounce handling. OpenSMTPD versiones anteriores a 6.6.4, permite una ejecución de código remota debido a una lectura fuera de límites en la función mta_io en el archivo mta_session.c para respuestas multilínea. Aunque esta vulnerabilidad afecta al lado del cliente de OpenSMTPD, es posible atacar a un servidor porque el código del servidor inicia el código del cliente durante el manejo de saltos. • https://www.exploit-db.com/exploits/48185 https://www.exploit-db.com/exploits/48140 http://packetstormsecurity.com/files/156633/OpenSMTPD-Out-Of-Bounds-Read-Local-Privilege-Escalation.html http://seclists.org/fulldisclosure/2020/Feb/32 http://www.openwall.com/lists/oss-security/2020/02/26/1 http://www.openwall.com/lists/oss-security/2020/03/01/1 http://www.openwall.com/lists/oss-security/2020/03/01/2 http://www.openwall.com/lists/oss-security/2021/05/04/7 https: • CWE-125: Out-of-bounds Read •
CVE-2020-8793 – OpenSMTPD 6.6.3 - Arbitrary File Read
https://notcve.org/view.php?id=CVE-2020-8793
OpenSMTPD before 6.6.4 allows local users to read arbitrary files (e.g., on some Linux distributions) because of a combination of an untrusted search path in makemap.c and race conditions in the offline functionality in smtpd.c. OpenSMTPD versiones anteriores a 6.6.4, permite a usuarios locales leer archivos arbitrarios (por ejemplo, en algunas distribuciones de Linux) debido a una combinación de una ruta de búsqueda no confiable en el archivo makemap.c y unas condiciones de carrera en la funcionalidad offline en el archivo smtpd.c. • https://www.exploit-db.com/exploits/48139 http://seclists.org/fulldisclosure/2020/Feb/28 http://www.openwall.com/lists/oss-security/2020/02/24/4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OPH4QU4DNVHA7ACFXMYFCEP5PSXXPN4E https://usn.ubuntu.com/4294-1 https://www.openbsd.org/security.html • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-426: Untrusted Search Path •
CVE-2020-1935 – tomcat: Mishandling of Transfer-Encoding header allows for HTTP request smuggling
https://notcve.org/view.php?id=CVE-2020-1935
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely. En Apache Tomcat versiones 9.0.0.M1 hasta 9.0.30, versiones 8.5.0 hasta 8.5.50 y versiones 7.0.0 hasta 7.0.99, el código de análisis del encabezado HTTP utilizó un enfoque para el análisis de fin de línea que permitió a algunos encabezados HTTP no válidos ser analizados como válidos. Esto conllevó a una posibilidad de Tráfico No Autorizado de Peticiones HTTP si Tomcat se encontraba detrás de un proxy inverso que manejaba incorrectamente el encabezado Transfer-Encoding no válido en una manera particular. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00025.html https://lists.apache.org/thread.html/r127f76181aceffea2bd4711b03c595d0f115f63e020348fe925a916c%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/r441c1f30a252bf14b07396286f6abd8089ce4240e91323211f1a2d75%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/r660cd379afe346f10d72c0eaa8459ccc95d83aff181671b7e9076919%40%3Cusers.tomcat.apache.org%3E https://lists.apache.org/thread.html/r7bc994c965a34876bd94d5ff15b4e1e30b6220a15eb9b47c81915b78%40%3Ccommits.tomee.apache.org%3E • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
