Mitigating speculative execution side channel hardware vulnerabilities

On January 3rd, 2018, Microsoft released an advisory and security updates related to a newly discovered class of hardware vulnerabilities involving speculative execution side channels known as Spectre and Meltdown that affect AMD, ARM, and Intel CPUs to varying degrees. If you haven’t had a chanc...

hw: cpu: speculative execution bounds-check bypass

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant...

UBUNTU-CVE-2017-18207

The Waveread.readfmtchunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service divide-by-zero and exception via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications...

CVE-2017-15862

In all Qualcomm products with Android releases from CAF using the Linux kernel, in wmaunifiedlinkradiostatseventhandler, the number of radio channels coming from firmware is not properly validated, potentially leading to an integer overflow vulnerability followed by a buffer overflow...

DEBIAN-CVE-2017-18189

In the startread function in xa.c in Sound eXchange SoX through 14.4.2, a corrupt header specifying zero channels triggers an infinite loop with a resultant NULL pointer dereference, which may allow a remote attacker to cause a denial-of-service...
