Vulnerability Details

CVEID:CVE-2022-4415
**DESCRIPTION:**systemd could allow a local authenticated attacker to obtain sensitive information, caused by not respecting fs.suid_dumpable kernel setting in the systemd-coredump. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/242796 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-3821
**DESCRIPTION:**systemd is vulnerable to a denial of service, caused by an off-by-one error in format_timespan() function of time-util.c. By sending specific values for time and accuracy, a local attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.5
