medium Nessus Plugin ID 123729

Language:

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

 - An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174.
 Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.i1/4^CVE-2018-18520i1/4%0

 - An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes.i1/4^CVE-2018-18310i1/4%0

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.

Solution

Update the affected elfutils packages.
