https://notcve.org/view.php?id=CVE-2018-1123
procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service). procps-ng en versiones anteriores a la 3.3.15 es vulnerable a una denegación de servicio (DoS) en ps mediante un desbordamiento de búfer en mmap. La protección incluida en ps mapea una página guard al final del búfer desbordado, asegurando que el impacto de este error se limita a un cierre inesperado (denegación de servicio temporal). Qualys performed an extensive audit of procps-ng. They discovered hundreds of bugs and vulnerabilities. • https://www.exploit-db.com/exploits/44806 https://github.com/aravinddathd/CVE-2018-1123 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 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1123 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2018-1125
procps-ng before version 3.3.15 is vulnerable to a stack buffer overflow in pgrep. This vulnerability is mitigated by FORTIFY, as it involves strncat() to a stack-allocated string. When pgrep is compiled with FORTIFY (as on Red Hat Enterprise Linux and Fedora), the impact is limited to a crash. procps-ng en versiones anteriores a la 3.3.15 es vulnerable a un desbordamiento de búfer basado en pila en pgrep. Esta vulnerabilidad se mitiga mediante FORTIFY, ya que implica el uso de strncat() en una cadena asignada a la pila. Cuando pgrep se compila con FORTIFY (como en Red Hat Enterprise Linux y Fedora), el impacto se limita a un cierre inesperado. • 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 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1125 https://lists.debian.org/debian-lts-announce/2018/05/msg00021.html https://usn.ubuntu.com/3658-1 https://usn.ubuntu.com/3658-3 https://www.debian.org/security/2018/dsa-4208 https:/ • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-1122
procps-ng before version 3.3.15 is vulnerable to a local privilege escalation in top. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function. procps-ng en versiones anteriores a la 3.3.15 es vulnerable a un escalado de privilegios locales en top. Si un usuario ejecuta top sin establecer HOME en un directorio controlado por el atacante, este podría lograr el escalado de privilegios explotando una de las varias vulnerabilidades existentes en la función config_file(). If the HOME environment variable is unset or empty, top will read its configuration file from the current working directory without any security check. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function. • 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 https://access.redhat.com/errata/RHSA-2019:2189 https://access.redhat.com/errata/RHSA-2020:0595 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1122 https://lists.debian.org/debian-lts-announce/2018/ • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

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: 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 •
