IBM Security Bulletin: IBM Spectrum Scale for IBM Elastic Storage Server is affected by the use of Local Read Only Cache (LROC) which may result in directory corruption and undetected data corruption in regular files.
The Elastic Storage Server is affected by a vulnerability in IBM Spectrum Scale where after cached data is moved from memory to the LROC device, any changes to that data should trigger invalidation of the data stored in LROC. Due to a problem with invalidation logic, it is possible for the invalidation of this LROC data to be skipped. This could lead to stale or incorrect data being recalled from LROC, with potential for the corruption of files and directories
CVE(s): CVE-2018-1993
Affected product(s) and affected version(s):
The Elastic Storage Server 5.3 thru 5.3.1.1
The Elastic Storage Server 5.0.0 thru 5.2.4
The Elastic Storage Server 4.5.0 thru 4.6.0
The Elastic Storage Server 4.0.0 thru 4.0.6
