Medium: udisks2

Issue Overview:

UDisks 2.8.0 has a format string vulnerability in udisks_log in udiskslogging.c, allowing attackers to obtain sensitive information (stack contents), cause a denial of service (memory corruption), or possibly have unspecified other impact via a malformed filesystem label, as demonstrated by %d or %n substrings.(CVE-2018-17336)

An uncontrolled format string vulnerability has been discovered in udisks when it mounts a filesystem with a malformed label. A local attacker may use this flaw to leak memory, make the udisks service crash, or cause other unspecified effects.(CVE-2018-17336)
