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

  - Elfutils is a collection of utilities, including stack     (to show backtraces), nm (for listing symbols from     object files), size (for listing the section sizes of     an object or archive file), strip (for discarding     symbols), readelf (to see the raw ELF file structures),     elflint (to check for well-formed ELF files) and     elfcompress (to compress or decompress ELF sections).
    Security Fix(es):In elfutils 0.175, a heap-based buffer     over-read was discovered in the function elf32_xlatetom     in elf32_xlatetom.c in libelf.

Remote attackers could leverage this     vulnerability to cause a denial-of-service via crafted     elf input, which leads to an out-of-memory exception.
    NOTE: The maintainers believe this is not a real issue,     but instead a 'warning caused by ASAN because the     allocation is big. By setting     ASAN_OPTIONS=allocator_may_return_null=1 and running     the reproducer, nothing happens.'(CVE-2019-7148)The

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

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3670-1 advisory.

    Agostino Sarubbo discovered that elfutils incorrectly handled certain malformed ELF files. If a user or     automated system were tricked into processing a specially crafted ELF file, elfutils could be made to     crash or consume resources, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
