An issue was discovered in aio_poll() in fs/aio.c in the Linux kernel through 5.0.4. A file may be released by aio_poll_wake() if an expected event is triggered immediately (e.g., by the close of a pair of pipes) after the return of vfs_poll(), and this will cause a use-after-free. Se ha descubierto un problema en aio_poll() en fs/aio.c en el kernel de Linux hasta la versión 5.0.4. aio_poll_wake() podría liberar un archivo si un evento esperado se desencadena inmediatamente (por ejemplo, al cerrar un par de tuberías) tras el retorno de vfs_poll(); esto provocará un uso de memoria previamente liberada. • http://www.securityfocus.com/bid/107655 https://patchwork.kernel.org/patch/10828359 https://security.netapp.com/advisory/ntap-20190411-0003 https://support.f5.com/csp/article/K29215970 • CWE-416: Use After Free •
CVSS: 6.5EPSS: 0%CPEs: 15EXPL: 0CVE-2019-3874 – kernel: SCTP socket buffer memory leak leading to denial of service
https://notcve.org/view.php?id=CVE-2019-3874
The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. El búfer del socket SCTP utilizado por una aplicación de espacio de usuario no es tenido en cuenta por el subsistema de cgroups. Un atacante podría explotar este error para lanzar un ataque de denegación de servicio. • https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3874 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://security.netapp.com/advisory/ntap-20190411-0003 https://usn.ubuntu.com/3979-1 https://usn.ubuntu.com/3980-1 https://usn.ubuntu.com/3980-2 https://usn.ubuntu.com/3981-1 https://usn.ubuntu.com/3981-2 https://usn.ubuntu.com/398 • CWE-400: Uncontrolled Resource Consumption •

An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation. Se ha descubierto un problema por el cual una dirección proporcionada con access_ok() no se comprueba en i915_gem_execbuffer2_ioctl en drivers/gpu/drm/i915/i915_gem_execbuffer.c en el kernel de Linux hasta la versión 4.19.13. Un atacante local puede manipular una llamada de función IOCTL para sobrescribir memoria arbitraria del kernel, lo que resulta en una denegación de servicio (DoS) o el escalado de privilegios. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/gpu/drm/i915/i915_gem_execbuffer.c http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://www.openwall.com/lists/oss-security/2019/01/23/6 http://www.securityfocus.com/bid/106748 https://access.redhat.com/security/cve/cve-2018-20669 https://security.netapp.com/advisory/ntap-20190404-0002 https://support.f5.com/csp/article/K32059550 https://usn.ubuntu.com/4485-1 • CWE-20: Improper Input Validation •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 2CVE-2019-9162 – Linux < 4.14.103 / < 4.19.25 - Out-of-Bounds Read and Write in SNMP NAT Module
https://notcve.org/view.php?id=CVE-2019-9162
In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper. En el kernel de Linux, en versiones anteriores a la 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c en el módulo SNMP NAT tiene comprobaciones de longitud ASN.1 insuficientes (conocido como error de índice de arrays), lo que hace que las operaciones de lectura y escritura fuera de límites sean posibles y conduciendo a un OOPS o al escalado de privilegios locales. Esto afecta a snmp_version y snmp_helper. • https://www.exploit-db.com/exploits/46477 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c4c07b4d6fa1f11880eab8e076d3d060ef3f55fc http://www.securityfocus.com/bid/107159 https://bugs.chromium.org/p/project-zero/issues/detail?id=1776 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.25 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.20.12 https://github.com/torvalds/linux/commit/c4c07b4d6fa1f11880eab8e076d3d060ef3f55fc https://security.netapp • CWE-787: Out-of-bounds Write •
