CVSS: 5.5EPSS: 0%CPEs: 32EXPL: 2CVE-2021-3744 – kernel: crypto: ccp - fix resource leaks in ccp_run_aes_gcm_cmd()
https://notcve.org/view.php?id=CVE-2021-3744
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808. Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función ccp_run_aes_gcm_cmd() en el archivo drivers/crypto/ccp/ccp-ops.c, que permite a atacantes causar una denegación de servicio (consumo de memoria). Esta vulnerabilidad es similar a la anterior CVE-2019-18808 A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to cause a denial of service. • http://www.openwall.com/lists/oss-security/2021/09/14/1 https://bugzilla.redhat.com/show_bug.cgi?id=2000627 https://github.com/torvalds/linux/commit/505d9dcb0f7ddf9d075e729523a33d38642ae680 https://kernel.googlesource.com/pub/scm/linux/kernel/git/herbert/crypto-2.6/+/505d9dcb0f7ddf9d075e729523a33d38642ae680%5E%21/#F0 https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7BLLVKYAIETEORUPTFO3TR3C33ZPFXQM https: • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.5EPSS: 0%CPEs: 13EXPL: 0CVE-2020-27842 – openjpeg: null pointer dereference in opj_tgt_reset function in lib/openjp2/tgt.c
https://notcve.org/view.php?id=CVE-2020-27842
There's a flaw in openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of this flaw is to application availability. Se presenta un fallo en el codificador t2 de openjpeg en versiones anteriores a 2.4.0. Un atacante que sea capaz de proporcionar una entrada diseñada para ser procesada por openjpeg podría causar una desreferencia del puntero null. • https://bugzilla.redhat.com/show_bug.cgi?id=1907513 https://lists.debian.org/debian-lts-announce/2022/04/msg00006.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WJUPGIZE6A4O52EBOF75MCXJOL6MUCRV https://security.gentoo.org/glsa/202101-29 https://www.debian.org/security/2021/dsa-4882 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuApr2021.html https://access.redhat.com/security/cve/CVE-2020-27842 • CWE-125: Out-of-bounds Read •
CVSS: 6.5EPSS: 0%CPEs: 324EXPL: 0CVE-2019-11135 – hw: TSX Transaction Asynchronous Abort (TAA)
https://notcve.org/view.php?id=CVE-2019-11135
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. Una condición de tipo TSX Asynchronous Abort en algunas CPU que utilizan ejecución especulativa puede habilitar a un usuario autenticado para permitir potencialmente una divulgación de información por medio de un canal lateral con acceso local. A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort (TAA) error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow information disclosure via this observed side-channel for any TSX transaction being executed while an attacker is able to observe abort timing. Intel's Transactional Synchronisation Extensions (TSX) are set of instructions which enable transactional memory support to improve performance of the multi-threaded applications, in the lock-protected critical sections. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00042.html http://packetstormsecurity.com/files/155375/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/12/10/3 http://www.openwall.com/lists/oss-security/2019/12/10/4 http://www.openwall.com/lists/oss-security/2019/12 • CWE-203: Observable Discrepancy •
