The vulnerability exists due to a boundary error when processing utf-8 strings in the pango_log2vis_get_embedding_levels() function in pango-bidi-type.c. A remote attacker can pass a specially crafted string to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Out-of-bounds write (CVE-ID: CVE-2019-14821)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the KVM coalesced MMIO support functionality due to incorrect processing of shared indexes. A local user can run a specially crafted application to trigger an out-of-bounds write error and write data to arbitrary address in the kernel memory.

Successful vulnerability exploitation may allow an attacker to execute arbitrary code on the system with root privileges.
