CVE-2019-13456 – freeradius: eap-pwd: Information leak due to aborting when needing more than 10 iterations
https://notcve.org/view.php?id=CVE-2019-13456
In FreeRADIUS 3.0 through 3.0.19, on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user. This information leakage is similar to the "Dragonblood" attack and CVE-2019-9494. En FreeRADIUS versiones 3.0 hasta 3.0.19, en promedio 1 de cada 2048 protocolos de enlace EAP-pwd presenta un fallo porque el elemento de contraseña no puede ser encontrado dentro de las 10 iteraciones del bucle de tipo "hunting and pecking". Esto filtra información que un atacante puede utilizar para recuperar la contraseña de cualquier usuario. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00039.html https://bugzilla.redhat.com/show_bug.cgi?id=1737663 https://freeradius.org/security https://github.com/FreeRADIUS/freeradius-server/commit/3ea2a5a026e73d81cd9a3e9bbd4300c433004bfa https://wpa3.mathyvanhoef.com https://access.redhat.com/security/cve/CVE-2019-13456 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVE-2019-14906 – SDL: not fixed in Red Hat Enterprise Linux 7 erratum RHSA-2019:3950
https://notcve.org/view.php?id=CVE-2019-14906
A flaw was found with the RHSA-2019:3950 erratum, where it did not fix the CVE-2019-13616 SDL vulnerability. This issue only affects Red Hat SDL packages, SDL versions through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer overflow flaw while copying an existing surface into a new optimized one, due to a lack of validation while loading a BMP image, is possible. An application that uses SDL to parse untrusted input files may be vulnerable to this flaw, which could allow an attacker to make the application crash or execute code. Se encontró un fallo con la errata de RHSA-2019: 3950, donde no se corrigió la vulnerabilidad SDL CVE-2019-13616. Este problema solo afecta a los paquetes SDL de Red Hat, SDL versiones hasta la versión 1.2.15 y versiones 2.x hasta la versión 2.0.9, tienen un fallo de desbordamiento de búfer en la región heap de la memoria mientras se copia una superficie existente en una nueva optimizada, debido a una falta de comprobación mientras la carga de una imagen BMP, es posible. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14906 https://access.redhat.com/security/cve/CVE-2019-14906 https://bugzilla.redhat.com/show_bug.cgi?id=1777372 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVE-2019-19319 – kernel: out-of-bounds write in ext4_xattr_set_entry in fs/ext4/xattr.c
https://notcve.org/view.php?id=CVE-2019-19319
In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30. En el kernel de Linux anterior a la versión 5.2, una operación setxattr, posterior al montaje de una imagen ext4 especialmente diseñada, puede causar un acceso de escritura fuera de límites debido a un uso de la memoria previamente liberada de la función ext4_xattr_set_entry en el archivo fs/ext4/xattr.c cuando se usa un valor grande de old_size en una llamada memset también conocido como CID-345c0dbf3a30. An out-of-bounds write flaw was found in the Linux kernel’s Ext4 FileSystem in the way it uses a crafted ext4 image. This flaw allows a local user with physical access to crash the system or potentially escalate their privileges on the system. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://bugzilla.suse.com/show_bug.cgi?id=1158021 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=345c0dbf3a30 https://github.com/bobfuzzer/CVE/tree/master/CVE-2019-19319 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
CVE-2019-18660 – kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
https://notcve.org/view.php?id=CVE-2019-18660
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. El kernel de Linux anterior a la versión 5.4.1 en powerpc permite la exposición de información porque la mitigación Spectre-RSB no está implementada para todas las CPU aplicables, también conocido como CID-39e72bf96f58. Esto está relacionado con arch / powerpc / kernel / entry_64.S y arch / powerpc / kernel / security.c. A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache (indirect branch cache) and Link (Return Address) Stack on the PowerPC platform. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/27/1 https://access.redhat.com/errata/RHSA-2020:0174 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=39e72bf96f5847ba87cc5bd7a3ce0fed813dc9ad https://lists.fedoraproject.org& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
