EulerOS Virtualization 3.0.2.6 : cpio (EulerOS-SA-2021-2911)

high Nessus Plugin ID 156542

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

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

- The cpio_safer_name_suffix function in util.c in cpio 2.11 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted cpio file. (CVE-2016-2037)

- GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.
(CVE-2021-38185)

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 cpio packages.
