CVSS: 7.8EPSS: 1%CPEs: 10EXPL: 0CVE-2018-10119 – libreoffice: Use-after-free in sdstor/stgstrms.cxx:StgSmallStrm class allows for denial of service with crafted document
https://notcve.org/view.php?id=CVE-2018-10119
sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format. sot/source/sdstor/stgstrms.cxx en LibreOffice, en versiones anteriores a la 5.4.5.1 y versiones 6.x anteriores a la 6.0.1.1, emplea un tipo de datos incorrecto en la clase StgSmallStrm. Esto permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada con acceso de escritura) o que puedan causar otro tipo de impacto sin especificar mediante un documento manipulado que emplea el formato contenedor de archivo ole2 de almacenamiento estructurado. • https://access.redhat.com/errata/RHSA-2018:3054 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=5747 https://gerrit.libreoffice.org/#/c/48751 https://gerrit.libreoffice.org/#/c/48756 https://gerrit.libreoffice.org/#/c/48757 https://gerrit.libreoffice.org/#/c/48758 https://gerrit.libreoffice.org/gitweb?p=core.git%3Ba=commit%3Bh=fdd41c995d1f719e92c6f083e780226114762f05 https://lists.debian.org/debian-lts-announce/2018/04/msg00021.html https://usn.ubuntu.com/3883- • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-10120
The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows remote attackers to cause a denial of service (heap-based buffer overflow with write access) or possibly have unspecified other impact via a crafted document that contains a certain Microsoft Word record. La función SwCTBWrapper::Read en sw/source/filter/ww8/ww8toolbar.cxx en LibreOffice, en versiones anteriores a la 5.4.6.1 y versiones 6.x anteriores a la 6.0.2.1, no valida un índice de personalizaciones.

CVSS: 7.8EPSS: 0%CPEs: 21EXPL: 0CVE-2018-7566 – kernel: race condition in snd_seq_write() may lead to UAF or OOB-access
https://notcve.org/view.php?id=CVE-2018-7566
The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user. El kernel de Linux 4.15 tiene un desbordamiento de búfer mediante una operación de escritura ioctl SNDRV_SEQ_IOCTL_SET_CLIENT_POOL en /dev/snd/seq por un usuario local. ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. • http://lists.opensuse.org/opensuse-security-announce/2018-03/msg00067.html http://mailman.alsa-project.org/pipermail/alsa-devel/2018-February/132026.html http://www.securityfocus.com/bid/103605 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2019:1483 https://access.redhat.com/errata/RHSA-2019:1487 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 9.8EPSS: 0%CPEs: 15EXPL: 0CVE-2018-5148 – firefox: Use-after-free in compositor potentially allows code execution
https://notcve.org/view.php?id=CVE-2018-5148
A use-after-free vulnerability can occur in the compositor during certain graphics operations when a raw pointer is used instead of a reference counted one. This results in a potentially exploitable crash. This vulnerability affects Firefox ESR < 52.7.3 and Firefox < 59.0.2. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada en el compositor durante determinadas operaciones de gráficos cuando un puntero raw se utiliza en vez de una de conteo de referencias. Esto resulta en un cierre inesperado explotable. • http://www.securityfocus.com/bid/103506 http://www.securitytracker.com/id/1040574 https://access.redhat.com/errata/RHSA-2018:1098 https://access.redhat.com/errata/RHSA-2018:1099 https://bugzilla.mozilla.org/show_bug.cgi?id=1440717 https://lists.debian.org/debian-lts-announce/2018/03/msg00023.html https://usn.ubuntu.com/3609-1 https://www.debian.org/security/2018/dsa-4153 https://www.mozilla.org/security/advisories/mfsa2018-10 https://access.redhat.com/security/cve/CVE& • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-1312
In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. En Apache httpd, en versiones desde la 2.2.0 hasta la 2.4.29, cuando se genera un desafío de autenticación HTTP Digest, el nonce enviado para evitar ataques replay no se generó correctamente empleando una semilla pseudoaleatoria. En un clúster de servidores, utilizando una configuración de autenticación Digest común, las peticiones HTTP se podrían reemplazar en los servidores por un atacante si que este sea detectado. • http://www.openwall.com/lists/oss-security/2018/03/24/7 http://www.securityfocus.com/bid/103524 http://www.securitytracker.com/id/1040571 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://access.redhat.com/errata/RHSA-2019:1898 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd. • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
