CVE-2019-2816 – OpenJDK: Missing URL format validation (Networking, 8221518)
https://notcve.org/view.php?id=CVE-2019-2816
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Networking). Supported versions that are affected are Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data as well as unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00044.html http://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html https://access.redhat.com/errata/RHSA-2019:2494 https://access.redhat.com/errata/RHSA-2019:2495 https://access.redhat.com/errata/RHSA-2019:2585 https://access.redhat.com/errata/RHSA-2019:2590 https://access.redhat.com/errata/RHSA-2019:2592 https://access.redhat.com • CWE-20: Improper Input Validation •
CVE-2019-2769 – OpenJDK: Unbounded memory allocation during deserialization in Collections (Utilities, 8213432)

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Utilities). Supported versions that are affected are Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.

CVE-2019-2786 – OpenJDK: Insufficient restriction of privileges in AccessController (Security, 8216381)
https://notcve.org/view.php?id=CVE-2019-2786
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00044.html http://www.oracle.com/technetwork/security-advisory/cpujul2019-5072835.html https://access.redhat.com/errata/RHSA-2019:2585 https://access.redhat.com/errata/RHSA-2019:2590 https://access.redhat.com/errata/RHSA-2019:2592 https://access.redhat.com/errata/RHSA-2019:2737 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_ •
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 •
