Amazon Linux 2 Security Advisory: ALAS-2022-1883
Advisory Release Date: 2022-12-01 20:31 Pacific
Advisory Updated Date: 2022-12-06 22:41 Pacific
Severity:
Important
Issue Overview:
multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR. (CVE-2022-41974)
Affected Packages:
device-mapper-multipath
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
