https://notcve.org/view.php?id=CVE-2020-12243
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: 8.8EPSS: 0%CPEs: 52EXPL: 6CVE-2020-8835 – Linux kernel bpf verifier vulnerability
https://notcve.org/view.php?id=CVE-2020-8835
In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka ZDI-CAN-10780) En el kernel de Linux versiones 5.5.0 y más recientes, el verificador bpf (kernel/bpf/verifier.c) no restringió apropiadamente los límites de registro para operaciones de 32 bits, conllevando a lecturas y escrituras fuera de límites en la memoria del kernel. La vulnerabilidad también afecta a la serie estable de Linux versión 5.4, comenzando con la versión v5.4.7, ya que el commit de introducción fue respaldado en esa derivación. • https://github.com/zilong3033/CVE-2020-8835 https://github.com/digamma-ai/CVE-2020-8835-verification https://github.com/SplendidSky/CVE-2020-8835 https://github.com/Prabhashaka/Exploitation-CVE-2020-8835 https://github.com/johnatag/INF8602-CVE-2020-8835 http://www.openwall.com/lists/oss-security/2021/07/20/1 https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=f2d67fec0b43edce8c416101cdc52e71145b5fef https://git.kernel.org/pub/scm/linux/kernel/git/torvald • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-8832
The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information. Se detectó que la solución para el kernel de Linux en Ubuntu versión 18.04 LTS para CVE-2019-14615 ("El kernel de Linux no borró apropiadamente las estructuras de datos en los conmutadores de contexto para determinados procesadores gráficos de Intel") estaba incompleta, lo que significa que en las versiones de kernel anteriores a 4.15.0-91.92, un atacante podría usar esta vulnerabilidad para exponer información confidencial. • https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862840 https://security.netapp.com/advisory/ntap-20200430-0004 https://usn.ubuntu.com/usn/usn-4302-1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
