DEBIAN-CVE-2019-7308

kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks...

Security Bulletin: IBM Security QRadar Packet Capture is vulnerable to 3RD PARTY CPU hardware utilizing speculative execution cache timing side-channel analysis known as Variant 4 or SpectreNG (CVE-2018-3639, CVE-2018-3640)

Summary Speculative execution is a technique used by many modern processors to improve performance by predicting which instructions may be executed based on past execution history. An attacker with local user access may be able to utilize sequences of speculative execution to perform a cache timi...
