CVE-2019-3890 – evolution-ews: all certificate errors ignored if error is ignored during initial account setup in gnome-online-accounts
https://notcve.org/view.php?id=CVE-2019-3890
It was discovered evolution-ews before 3.31.3 does not check the validity of SSL certificates. An attacker could abuse this flaw to get confidential information by tricking the user into connecting to a fake server without the user noticing the difference. Se detectó que evolution-ews anterior a versión 3.31.3, no comprueba la validez de los certificados SSL. Un atacante podría abusar de este fallo para conseguir información confidencial mediante el engaño del usuario para que se conecte a un servidor falso sin que el usuario note la diferencia.

CVE-2019-14379 – jackson-databind: default typing mishandling leading to remote code execution
https://notcve.org/view.php?id=CVE-2019-14379
SubTypeValidator.java in FasterXML jackson-databind before 2.9.9.2 mishandles default typing when ehcache is used (because of net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), leading to remote code execution. El archivo SubTypeValidator.java en jackson-databind de FasterXML en versiones anteriores a la 2.9.9.2 maneja inapropiadamente la escritura predeterminada cuando se usa ehcache (debido a net.sf.ehcache.transaction.manager.DefaultTransactionManagerLookup), lo que conlleva a la ejecución de código remoto. A flaw was discovered in FasterXML jackson-databind, where it would permit polymorphic deserialization of malicious objects using the ehcache and logback JNDI gadgets when used in conjunction with polymorphic type handling methods such as `enableDefaultTyping()` or when @JsonTypeInfo is using `Id.CLASS` or `Id.MINIMAL_CLASS` or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. An attacker could use this flaw to execute arbitrary code. • http://seclists.org/fulldisclosure/2022/Mar/23 https://access.redhat.com/errata/RHBA-2019:2824 https://access.redhat.com/errata/RHSA-2019:2743 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-2019:2998 https://access.redhat.com/errata/RHSA-2 • CWE-502: Deserialization of Untrusted Data CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •

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 •
