CVSS: 7.0EPSS: 0%CPEs: 44EXPL: 0CVE-2020-11884 – Kernel: s390: page table upgrade in secondary address mode may lead to privilege escalation
https://notcve.org/view.php?id=CVE-2020-11884
In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur. En el kernel de Linux versión 4.9 hasta la versión 5.6.7, en la plataforma s390, una ejecución de código puede presentarse debido a una condición de carrera, como es demostrado por el código en la función enable_sacf_uaccess en el archivo arch/s390/lib/uaccess.c que presenta un fallo al proteger contra una actualización concurrente de la tabla de página, también se conoce como CID-3f777e19d171. Tambíen podría ocurrir un bloqueo A flaw was found in the Linux kernel on s390 architecture. The issue occurs on multiprocessing systems when one s390 CPU is in Secondary Address Mode and another CPU does a kernel page table upgrade. • https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=215d1f3928713d6eaec67244bcda72105b898000 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3f777e19d171670ab558a6d5e6b1ac7f9b6c574f https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3TZBP2HINNAX7HKHCOUMIFVQPV6GWMCZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AQUVKC3IPUC5B374VVAZV4J5P3GAUGSW https://lists.fedoraproject.org/archives/list/package-announce%4 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-1251: Mirrored Regions with Different Values •

In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash). En el archivo filter.c en slapd en OpenLDAP versiones anteriores a 2.4.50, los filtros de búsqueda de LDAP con expresiones booleanas anidadas pueden resultar en una denegación de servicio (bloqueo del demonio). • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00016.html https://bugs.openldap.org/show_bug.cgi?id=9202 https://git.openldap.org/openldap/openldap/-/blob/OPENLDAP_REL_ENG_2_4/CHANGES https://git.openldap.org/openldap/openldap/-/commit/98464c11df8247d6a11b52e294ba5dd4f0380440 https://lists.debian.org/debian-lts-announce/2020/05/msg00001.html https://security.netapp.com/advisory/ntap-20200511-0003 https://support.apple.com/kb/HT211289 https://usn.ubuntu.com/4352-1 https&# • CWE-400: Uncontrolled Resource Consumption CWE-674: Uncontrolled Recursion •
CVSS: 7.5EPSS: 8%CPEs: 38EXPL: 1CVE-2020-1967 – Segmentation fault in SSL_check_chain
https://notcve.org/view.php?id=CVE-2020-1967
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. • https://github.com/irsl/CVE-2020-1967 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00011.html http://packetstormsecurity.com/files/157527/OpenSSL-signature_algorithms_cert-Denial-Of-Service.html http://seclists.org/fulldisclosure/2020/May/5 http://www.openwall.com/lists/oss-security/2020/04/22/2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=eb563247aef3e83dda7679c43f9649270462e5b1 https:/&# • CWE-476: NULL Pointer Dereference •
