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 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 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 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 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.
