Description

This security bulletin contains information about 1 vulnerability.


1) Format string error (CVE-ID: CVE-2018-17336)

CWE-ID: CWE-134 - Use of Externally-Controlled Format String

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a format string error in udisks_log in udiskslogging.c. A local user can supply a specially crafted input that contains format string specifiers to obtain sensitive information (stack contents), cause a denial of service (memory corruption), or possibly have unspecified other impact via a malformed filesystem label.
