Abstract
These vulnerabilities allow local users to obtain sensitive information via a susceptible version of Synology DiskStation Manager (DSM), Synology Router Manager (SRM), and VisualStation running on an Intel or Arm CPU, even if in Virtual Machine Manager.
Synology rates the overall severity as Moderate because these vulnerabilities can only be exploited via local malicious programs. To secure customers' products against the attacks, we recommend you only install trusted packages.
Regarding Spectre & Meltdown Checker, Synology implements array_index_mask_nospec
, minimal ASM retpoline, Kernel Page Table Isolation (KPTI) into affected models [1], and additional Indirect Branch Prediction Barrier (IBPB) into specific models [2] to mitigate the vulnerabilities for DSM.
Our customers can mitigate the vulnerabilities in both DSM and SRM by upgrading to 6.2.2-24922 and 1.1.7-6941-1, respectively.
