UBUNTU-CVE-2018-1122 (CVE-2018-1122)

Vulnerability from osv_ubuntu – Published: 2018-05-17 17:00 – Updated: 2026-04-22 07:38 – Source website

Details

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.

Severity

7.0 (High)

UBUNTU-CVE-2018-1123 (CVE-2018-1123)

Vulnerability from osv_ubuntu – Published: 2018-05-17 17:00 – Updated: 2026-04-22 07:38 – Source website

Details

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).

UBUNTU-CVE-2018-1124 (CVE-2018-1124)

Vulnerability from osv_ubuntu – Published: 2018-05-17 17:00 – Updated: 2026-04-22 07:38 – Source website

Details

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.

Severity

7.8 (High)

UBUNTU-CVE-2018-1125 (CVE-2018-1125)

Vulnerability from osv_ubuntu – Published: 2018-05-17 17:00 – Updated: 2026-04-22 07:38 – Source website

Details

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.
