CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 1CVE-2018-1126 – procps: incorrect integer size in proc/alloc.* leading to truncation / integer overflow issues
https://notcve.org/view.php?id=CVE-2018-1126
procps-ng before version 3.3.15 is vulnerable to an incorrect integer size in proc/alloc.* leading to truncation/integer overflow issues. This flaw is related to CVE-2018-1124. procps-ng en versiones anteriores a la 3.3.15 es vulnerable a un tamaño de entero incorrecto en proc/alloc.* que conduce a problemas de truncado/desbordamiento de enteros. Este error está relacionado con CVE-2018-1124. A flaw was found where procps-ng provides wrappers for standard C allocators that took `unsigned int` instead of `size_t` parameters. On platforms where these differ (such as x86_64), this could cause integer truncation, leading to undersized regions being returned to callers that could then be overflowed. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00059.html http://seclists.org/oss-sec/2018/q2/122 http://www.securityfocus.com/bid/104214 http://www.securitytracker.com/id/1041057 https://access.redhat.com/errata/RHSA-2018:1700 https://access.redhat.com/errata/RHSA-2018:1777 https://access.redhat.com/errata/RHSA-2018:1820 https://access.redhat.com/errata/RHSA-2018:2267 https://access • CWE-190: Integer Overflow or Wraparound •
CVSS: 7.8EPSS: 0%CPEs: 20EXPL: 2CVE-2018-1124 – Procps-ng - Multiple Vulnerabilities
https://notcve.org/view.php?id=CVE-2018-1124
procps-ng before version 3.3.15 is vulnerable to multiple integer overflows leading to a heap corruption in file2strvec function. This allows a privilege escalation for a local attacker who can create entries in procfs by starting processes, which could result in crashes or arbitrary code execution in proc utilities run by other users. procps-ng en versiones anteriores a la 3.3.15 es vulnerable a múltiples desbordamientos de enteros que conducen a una corrupción de la memoria dinámica (heap) en la función file2strvec. Esto permite el escalado de privilegios para un atacante local que puede crear entradas en procfs empezando procesos, lo que podría resultar en cierres inesperados o la ejecución de código arbitrario en las utilidades proc ejecutadas por otros usuarios. Multiple integer overflows leading to heap corruption flaws were discovered in file2strvec(). These vulnerabilities can lead to privilege escalation for a local attacker who can create entries in procfs by starting processes, which will lead to crashes or arbitrary code execution in proc utilities run by other users (eg pgrep, pkill, pidof, w). • https://www.exploit-db.com/exploits/44806 http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00059.html http://seclists.org/oss-sec/2018/q2/122 http://www.securityfocus.com/bid/104214 http://www.securitytracker.com/id/1041057 https://access.redhat.com/errata/RHSA-2018:1700 https://access.redhat.com/errata/RHSA-2018:1777 https://access.redhat.com/errata/RHSA-2018:1820 https://access.redha • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
CVSS: 5.6EPSS: 0%CPEs: 665EXPL: 5CVE-2018-3639 – AMD / ARM / Intel - Speculative Execution Variant 4 Speculative Store Bypass
https://notcve.org/view.php?id=CVE-2018-3639
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2018-11237
An AVX-512-optimized implementation of the mempcpy function in the GNU C Library (aka glibc or libc6) 2.27 and earlier may write data beyond the target buffer, leading to a buffer overflow in __mempcpy_avx512_no_vzeroupper. Una implementación optimizada para AVX-512 de la función mempcpy en GNU C Library (también conocido como glibc o libc6), en versiones 2.27 y anteriores, podría escribir datos más allá del búfer objetivo, lo que desemboca en un desbordamiento de búfer en __mempcpy_avx512_no_vzeroupper. A buffer overflow has been discovered in the GNU C Library (aka glibc or libc6) in the __mempcpy_avx512_no_vzeroupper function when particular conditions are met. An attacker could use this vulnerability to cause a denial of service or potentially execute code. GNU glibc versions prior to 2.27 suffer from a buffer overflow vulnerability. • http://www.securityfocus.com/bid/104256 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190329-0001 https://security.netapp.com/advisory/ntap-20190401-0001 https://sourceware.org/bugzilla/show_bug.cgi?id=23196 https://usn.ubuntu.com/4416-1 https://www.exploit-db.com/exploits/44750 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/security • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-11236
stdlib/canonicalize.c in the GNU C Library (aka glibc or libc6) 2.27 and earlier, when processing very long pathname arguments to the realpath function, could encounter an integer overflow on 32-bit architectures, leading to a stack-based buffer overflow and, potentially, arbitrary code execution. stdlib/canonicalize.c en GNU C Library (también conocida como glibc o libc6), en versiones 2.27 y anteriores, al procesar argumentos con un nombre de ruta muy largo en la función realpath, podría encontrarse con un desbordamiento de enteros en arquitecturas de 32 bits. Esto podría desembocar en un desbordamiento de búfer basado en pila y en una potencial ejecución de código arbitrario. • http://www.securityfocus.com/bid/104255 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3092 https://security.netapp.com/advisory/ntap-20190329-0001 https://security.netapp.com/advisory/ntap-20190401-0001 https://sourceware.org/bugzilla/show_bug.cgi?id=22786 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Bh=5460617d1567657621107d895ee2dd83bc1f88f2 https://usn.ubuntu.com/4416-1 https://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.h • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
