CVSS: 9.8EPSS: 0%CPEs: 20EXPL: 0CVE-2018-6485 – glibc: Integer overflow in posix_memalign in memalign functions
https://notcve.org/view.php?id=CVE-2018-6485
An integer overflow in the implementation of the posix_memalign in memalign functions in the GNU C Library (aka glibc or libc6) 2.26 and earlier could cause these functions to return a pointer to a heap area that is too small, potentially leading to heap corruption. Un desbordamiento de enteros en la implementación de posix_memalign en las funciones memalign en GNU C Library (también conocido como glibc o libc6) en versiones 2.26 y anteriores podría provocar que estas funciones devuelvan un puntero a un área de la memoria dinámica (heap) demasiado pequeña, pudiendo corromper el heap. • http://bugs.debian.org/878159 http://www.securityfocus.com/bid/102912 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190404-0003 https://sourceware.org/bugzilla/show_bug.cgi?id=22343 https://usn.ubuntu.com/4218-1 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security/cve/CVE-2018-6485 https:/ • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

CVSS: 7.8EPSS: 81%CPEs: 41EXPL: 32CVE-2016-5195 – Linux Kernel Race Condition Vulnerability
https://notcve.org/view.php?id=CVE-2016-5195
Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW." La condición de carrera en mm / gup.c en el kernel de Linux 2.x a 4.x antes de 4.8.3 permite a los usuarios locales obtener privilegios aprovechando el manejo incorrecto de una función copy-on-write (COW) para escribir en un read- only la cartografía de la memoria, como explotados en la naturaleza en octubre de 2016, vulnerabilidad también conocida como "Dirty COW". A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system. Race condition in mm/gup.c in the Linux kernel allows local users to escalate privileges. • https://github.com/dirtycow/dirtycow.github.io https://www.exploit-db.com/exploits/40611 https://www.exploit-db.com/exploits/40838 https://www.exploit-db.com/exploits/40616 https://www.exploit-db.com/exploits/40839 https://www.exploit-db.com/exploits/40847 https://github.com/timwr/CVE-2016-5195 https://github.com/gbonacini/CVE-2016-5195 https://github.com/whu-enjoy/CVE-2016-5195 https://github.com/jas502n/CVE-2016-5195 https://github.com/arttnba3/CVE-2016- • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
