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 •

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 •
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 •
