The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - procps-ng, procps: process hiding through race condition enumerating /proc (CVE-2018-1121)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - procps-ng, procps: process hiding through race condition enumerating /proc (CVE-2018-1121)

  - 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). (CVE-2018-1123)

  - 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. (CVE-2018-1125)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - procps-ng, procps: Local privilege escalation in top (CVE-2018-1122)

  - procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's     proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use     inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID,     thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by     exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng     up to version 3.3.15, newer versions might be affected also. (CVE-2018-1121)

  - 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). (CVE-2018-1123)

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - procps-ng, procps: incorrect integer size in proc/alloc.* leading to truncation / integer overflow issues     (CVE-2018-1126)

  - procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's     proc_pid_readdir() returns PID entries in ascending numeric order, a process occupying a high PID can use     inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower PID,     thus avoiding enumeration. An unprivileged attacker can hide a process from procps-ng's utilities by     exploiting a race condition in reading /proc/PID entries. This vulnerability affects procps and procps-ng     up to version 3.3.15, newer versions might be affected also. (CVE-2018-1121)

  - 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. (CVE-2018-1122)
