ALAS2-2019-1280


Amazon Linux 2 Security Advisory: ALAS-2019-1280
Advisory Release Date: 2019-09-19 16:05 Pacific
Severity: Medium

Issue Overview:

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 )


It 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 )
