CVE-2019-13272 – Linux Kernel Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2019-13272
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. En el kernel de Linux anterior a versión 5.1.17, ptrace_link en el archivo kernel/ptrace.c maneja inapropiadamente la grabación de las credenciales de un proceso que desea crear una relación de ptrace, que permite a los usuarios locales obtener acceso de root aprovechando determinados escenarios con un relación de proceso padre-hijo, donde un padre elimina los privilegios y llama a execve (permitiendo potencialmente el control por parte de un atacante). • https://www.exploit-db.com/exploits/47133 https://www.exploit-db.com/exploits/47163 https://www.exploit-db.com/exploits/50541 https://www.exploit-db.com/exploits/47543 https://github.com/jas502n/CVE-2019-13272 https://github.com/Cyc1eC/CVE-2019-13272 https://github.com/oneoy/CVE-2019-13272 https://github.com/polosec/CVE-2019-13272 https://github.com/MDS1GNAL/ptrace_scope-CVE-2019-13272-privilege-escalation https://github.com/datntsec/CVE-2019-13272 https://github • CWE-271: Privilege Dropping / Lowering Errors •
CVE-2019-13616 – SDL: heap-based buffer overflow in SDL blit functions in video/SDL_blit*.c
https://notcve.org/view.php?id=CVE-2019-13616
SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer over-read in BlitNtoN in video/SDL_blit_N.c when called from SDL_SoftBlit in video/SDL_blit.c. hasta 2.0.9, presenta una lectura excesiva del búfer en la región heap de la memoria en BlitNtoN en el archivo video/SDL_blit_N.c cuando es llamado desde SDL_SoftBlit en el archivo video/SDL_blit.c. A heap-based buffer overflow was discovered in SDL in the SDL_BlitCopy() function, that was called while copying an existing surface into a new optimized one, due to lack of validation while loading a BMP image in the SDL_LoadBMP_RW() function. An application that uses SDL to parse untrusted input files may be vulnerable to this flaw, which could allow an attacker to make the application crash or possibly execute code. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00030.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00093.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00094.html https://access.redhat.com/errata/RHSA-2019:3950 https:/ • CWE-125: Out-of-bounds Read •
CVE-2019-12384 – jackson-databind: failure to block the logback-core class from polymorphic deserialization leading to remote code execution
https://notcve.org/view.php?id=CVE-2019-12384
FasterXML jackson-databind 2.x before 2.9.9.1 might allow attackers to have a variety of impacts by leveraging failure to block the logback-core class from polymorphic deserialization. Depending on the classpath content, remote code execution may be possible. FasterXML jackson-databind versión 2.x anterior a 2.9.9.1, podría permitir a los atacantes dirigir una variedad de impactos al aprovechar un fallo al bloquear la deserialización polimórfica de la clase core-logback. Dependiendo del contenido del classpath, la ejecución de código remota puede ser posible. A flaw was discovered in FasterXML jackson-databind in versions prior to 2.9.9. • https://github.com/jas502n/CVE-2019-12384 https://github.com/MagicZer0/Jackson_RCE-CVE-2019-12384 https://access.redhat.com/errata/RHSA-2019:1820 https://access.redhat.com/errata/RHSA-2019:2720 https://access.redhat.com/errata/RHSA-2019:2858 https://access.redhat.com/errata/RHSA-2019:2935 https://access.redhat.com/errata/RHSA-2019:2936 https://access.redhat.com/errata/RHSA-2019:2937 https://access.redhat.com/errata/RHSA-2019:2938 https://access.redhat.com/errata/RHSA& • CWE-502: Deserialization of Untrusted Data •
CVE-2019-11038 – Uninitialized read in gdImageCreateFromXbm
https://notcve.org/view.php?id=CVE-2019-11038
When using the gdImageCreateFromXbm() function in the GD Graphics Library (aka LibGD) 2.2.5, as used in the PHP GD extension in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is possible to supply data that will cause the function to use the value of uninitialized variable. This may lead to disclosing contents of the stack that has been left there by previous code. Cuando se usa la función gdImageCreateFromXbm () en la Biblioteca de gráficos GD (también conocida como LibGD) 2.2.5, como se usa en la extensión PHP GD en las versiones de PHP 7.1.x debajo de 7.1.30, 7.2.x debajo de 7.2.19 y 7.3.x debajo 7.3.6, es posible suministrar datos que harán que la función use el valor de la variable no inicializada. Esto puede llevar a revelar el contenido de la pila que ha quedado allí por código anterior. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00020.html https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=929821 https://bugs.php.net/bug.php?id=77973 https://bugzilla.redhat.com/show_bug.cgi?id=1724149 https://bugzilla.redhat.com/show_bug.cgi?id=1724432 https://bugzilla.suse.com/show_bug.cgi? • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-457: Use of Uninitialized Variable CWE-908: Use of Uninitialized Resource •
