Vulnerability Details

CVEID: CVE-2018-1126 DESCRIPTION: procps-ng procps is vulnerable to a buffer overflow, caused by improper bounds checking. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/143456&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2018-1125 DESCRIPTION: procps-ng procps is vulnerable to a stack-based buffer overflow, caused by improper bounds checking. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/143455&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2018-1124 DESCRIPTION: procps-ng procps could allow a local authenticated attacker to gain elevated privileges on the system, caused by an integer overflow in the file2strvec function in libprocps. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base Score: 7.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/143454&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-1123 DESCRIPTION: procps-ng procps is vulnerable to a denial of service, caused by a mmap-based buffer overflow flaw in the ps function. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/143453&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-1122 DESCRIPTION: procps-ng procps could allow a local authenticated attacker to gain elevated privileges on the system, caused by a flaw when the HOME environment variable is unset or empty. By sending a specially-crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base Score: 7.8
