SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionIt was found that paravirt_patch_call/jump() functions in the arch/x86/kernel/paravirt.c in the Linux kernel mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtualized guests.(CVE-2018-15594)
A buffer overflow due to a singed-unsigned comparsion was found in hidp_process_report() in the net/bluetooth/hidp/core.c in the Linux kernel. The buffer length is an unsigned int but gets cast to a signed int which in certain conditions can lead to a system panic and a denial-of-service.(CVE-2018-9363)
Note: The Release Date is incorrect. These CVEs were fixed Sept. 2018
SolutionRun 'yum update kernel' and restart the instance to update your system.
