CVE-2018-17581 – exiv2: Stack overflow in CiffDirectory::readDirectory() at crwimage_int.cpp leading to denial of service
https://notcve.org/view.php?id=CVE-2018-17581
CiffDirectory::readDirectory() at crwimage_int.cpp in Exiv2 0.26 has excessive stack consumption due to a recursive function, leading to Denial of service. CiffDirectory::readDirectory() en crwimage_int.cpp en Exiv2 0.26 tiene un consumo excesivo de pila debido a una función recursiva, lo que conduce a una denegación de servicio (DoS). • https://access.redhat.com/errata/RHSA-2019:2101 https://github.com/Exiv2/exiv2/issues/460 https://github.com/SegfaultMasters/covering360/blob/master/Exiv2 https://lists.debian.org/debian-lts-announce/2019/02/msg00038.html https://lists.debian.org/debian-lts-announce/2023/01/msg00004.html https://usn.ubuntu.com/3852-1 https://access.redhat.com/security/cve/CVE-2018-17581 https://bugzilla.redhat.com/show_bug.cgi?id=1635045 • CWE-400: Uncontrolled Resource Consumption •
CVE-2018-14650 – sos-collector: incorrect permissions set on newly created files
https://notcve.org/view.php?id=CVE-2018-14650
It was discovered that sos-collector does not properly set the default permissions of newly created files, making all files created by the tool readable by any local user. A local attacker may use this flaw by waiting for a legit user to run sos-collector and steal the collected data in the /var/tmp directory. Se ha descubierto que sos-collector no establece correctamente los permisos por defecto de los nuevos archivos creados, haciendo que todos los archivos creados por la herramienta puedan ser leídos por cualquier usuario local. Un atacante local podría utilizar este error esperando a que un usuario legítimo ejecute sos-collector y robe los datos recopilados en el directorio /var/tmp. • https://access.redhat.com/errata/RHSA-2018:3663 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14650 https://github.com/sosreport/sos-collector/commit/72058f9253e7ed8c7243e2ff76a16d97b03d65ed https://access.redhat.com/security/cve/CVE-2018-14650 https://bugzilla.redhat.com/show_bug.cgi?id=1633243 • CWE-276: Incorrect Default Permissions CWE-732: Incorrect Permission Assignment for Critical Resource •
CVE-2018-14634 – Linux Kernel 2.6.x / 3.10.x / 4.14.x (RedHat / Debian / CentOS) (x64) - 'Mutagen Astronomy' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-14634
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable. Se ha encontrado un error de desbordamiento de enteros en la función create_elf_tables() del kernel de Linux. Un usuario local sin privilegios con acceso al binario SUID (o a otro privilegiado) podría emplear este error para escalar sus privilegios en el sistema. • https://www.exploit-db.com/exploits/45516 http://www.openwall.com/lists/oss-security/2021/07/20/2 http://www.securityfocus.com/bid/105407 https://access.redhat.com/errata/RHSA-2018:2748 https://access.redhat.com/errata/RHSA-2018:2763 https://access.redhat.com/errata/RHSA-2018:2846 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018:2925 https://access.redhat.com/errata/RHSA-2018:2933 https://access.redhat.com/errata/RHSA- • CWE-190: Integer Overflow or Wraparound •
CVE-2018-12385 – Mozilla: Crash in TransportSecurityInfo due to cached data
https://notcve.org/view.php?id=CVE-2018-12385
A potentially exploitable crash in TransportSecurityInfo used for SSL can be triggered by data stored in the local cache in the user profile directory. This issue is only exploitable in combination with another vulnerability allowing an attacker to write data into the local cache or from locally installed malware. This issue also triggers a non-exploitable startup crash for users switching between the Nightly and Release versions of Firefox if the same profile is used. This vulnerability affects Thunderbird < 60.2.1, Firefox ESR < 60.2.1, and Firefox < 62.0.2. Un cierre inesperado potencialmente explotable en TransportSecurityInfo empleado para SSL puede desencadenarse por los datos almacenados en la caché local en el directorio de perfil del usuario. • http://www.securityfocus.com/bid/105380 http://www.securitytracker.com/id/1041700 http://www.securitytracker.com/id/1041701 https://access.redhat.com/errata/RHSA-2018:2834 https://access.redhat.com/errata/RHSA-2018:2835 https://access.redhat.com/errata/RHSA-2018:3403 https://access.redhat.com/errata/RHSA-2018:3458 https://bugzilla.mozilla.org/show_bug.cgi?id=1490585 https://lists.debian.org/debian-lts-announce/2018/11/msg00011.html https://security.gentoo.org/glsa/201810- • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2018-14647 – python: Missing salt initialization in _elementtree.c module
https://notcve.org/view.php?id=CVE-2018-14647
Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. El acelerador de C elementtree en Python no inicializa la sal del hash Expat durante la inicialización. Esto podría facilitar llevar a cabo ataques de denegación de servicio (DoS) contra Expat construyendo un documento XML que provocaría colisiones de hashes en las estructuras internas de datos de Expat, consumiendo grandes cantidades de CPU y RAM. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/105396 http://www.securitytracker.com/id/1041740 https://access.redhat.com/errata/RHSA-2019:1260 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue34623 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14647 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.boo • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •
