CVE-2019-5108 – kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS
https://notcve.org/view.php?id=CVE-2019-5108
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability. Se presenta una vulnerabilidad de denegación de servicio explotable en el kernel de Linux anterior a mainline 5.3. • http://packetstormsecurity.com/files/156455/Kernel-Live-Patch-Security-Notice-LSN-0063-1.html https://git.kernel.org/linus/3e493173b7841259a08c5c8e5cbe90adb349da7e 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-20200204-0002 https://talosintelligence.com/vulnerability_reports/TALOS-2019-0900 https://usn.ubuntu.com • CWE-287: Improper Authentication CWE-440: Expected Behavior Violation •
CVE-2019-11050 – Use-after-free in exif parsing under memory sanitizer
https://notcve.org/view.php?id=CVE-2019-11050
When PHP EXIF extension is parsing EXIF information from an image, e.g. via exif_read_data() function, in PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to supply it with data what will cause it to read past the allocated buffer. This may lead to information disclosure or crash.

CVE-2019-11046 – Buffer underflow in bc_shift_addsub
https://notcve.org/view.php?id=CVE-2019-11046
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations. En PHP versiones 7.2.x por debajo de 7.2.26, versiones 7.3.x por debajo de 7.3.13 y 7.4.0, las funciones de extensión bcmath de PHP en algunos sistemas, incluyendo Windows, pueden ser engañadas para que lean más allá del espacio asignado al suministrarle cadenas que contengan caracteres que el sistema operativo identifica como numéricos pero no son números ASCII. Esto puede ser leído para revelar el contenido de algunas ubicaciones de memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00036.html https://bugs.php.net/bug.php?id=78878 https://lists.debian.org/debian-lts-announce/2019/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N7GCOAE6KVHYJ3UQ4KLPLTGSLX6IRVRN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWRQPYXVG43Q7DXMXH6UVWMKWGUW552F https://seclists.org/bugtraq/2020/Feb/27 https://seclists.org/bugtraq/2020/Feb/31 ht • CWE-125: Out-of-bounds Read •
CVE-2019-11045 – DirectoryIterator class silently truncates after a null byte
https://notcve.org/view.php?id=CVE-2019-11045
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access. En PHP versiones 7.2.x por debajo de 7.2.26, versiones 7.3.x por debajo de 7.3.13 y 7.4.0, la clase DirectoryIterator de PHP acepta nombres de archivo con \0 byte insertado y los trata como terminando en ese byte. Esto podría conllevar a vulnerabilidades de seguridad, por ejemplo en aplicaciones que comprueban las rutas a las que se permite acceder al código. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00036.html https://bugs.php.net/bug.php?id=78863 https://lists.debian.org/debian-lts-announce/2019/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N7GCOAE6KVHYJ3UQ4KLPLTGSLX6IRVRN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWRQPYXVG43Q7DXMXH6UVWMKWGUW552F https://seclists.org/bugtraq/2020/Feb/27 https://seclists.org/bugtraq/2020/Feb/31 ht • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-170: Improper Null Termination •
