Linux Kernel Vulnerabilities Affecting The Selective ACK Component

On June 18th 2019 at 7pm CEST, 4 vulnerabilities have been disclosed affecting the TCP stack of the Linux kernel. These vulnerabilities relies on an integer overflow in the Linux kernel which can lead to a kernel panic on one hand, and on an algorithmic complexity in the SACK implementation leading to CPU resource exhaustion …

RAMBleed DRAM

RAMBleed DRAM

On June 11th, security researchers published a paper titled “RAMBleed Reading Bits in Memory without Accessing Them”.  This paper describes vector  against Dynamic Random Access Memory (DRAM) modules that are already susceptible toRowhammer-style attacks. Systems using DRAM modules mitigated against Rowhammer style attacks remain protected from RAMBleed.  This vector may affects hardware products, among which some used by OVH. …
