Positive Technologies (AI Summary)

CVSS v3.1

9.1

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

Name of the Vulnerable Software and Affected Versions glibc versions prior to 2.23

Description The issue allows context-dependent attackers to cause a denial of service, potentially leading to an application crash, or possibly obtain sensitive information via an out-of-range time value. This is related to the strftime function in the GNU C Library.

Recommendations For versions prior to 2.23, update to version 2.23 or later to resolve the issue. As a temporary workaround, consider restricting the input to the strftime function to prevent out-of-range time values until a patch is available.
