Use of IBM Spectrum Scale on an Elastic Storage Server/GPFS Storage Server in an unsupported configuration, where user applications are running on an active ESS I/O server node and utilize direct I/O to perform a read or a write to a Spectrum Scale file, may result in a daemon failure, possibly leading to denial of service or undetected data corruption.
CVEID: CVE-2017-1304**
DESCRIPTION:** IBM has identified a vulnerability with IBM Spectrum Scale/GPFS utilized on the Elastic Storage Server (ESS)/GPFS Storage Server (GSS) during testing of an unsupported configuration, where users applications are running on an active ESS I/O server node and utilize direct I/O to perform a read or a write to a Spectrum Scale file. This vulnerability may result in the use of an incorrect memory address, leading to a Spectrum Scale/GPFS daemon failure with a Signal 11, and possibly leading to denial of service or undetected data corruption.
