Description

According to the versions of the libmirage package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  • libMirage 3.2.2 in CDemu has a NULL pointer dereference in the NRG parser in parser.c.(CVE-2019-15757)

  • filters/filter-cso/filter-stream.c in the CSO filter in libMirage 3.2.2 in CDemu does not validate the part size, triggering a heap-based buffer overflow that can lead to root access by a local Linux user.(CVE-2019-15540)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
