EulerOS Virtualization 3.0.2.2 : gnupg2 (EulerOS-SA-2020-1489)

medium Nessus Plugin ID 135651

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the gnupg2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence.(CVE-2014-4617)

- kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and 'memcpy with overlapping ranges.'(CVE-2015-1607)

- The keyring DB in GnuPG before 2.1.2 does not properly handle invalid packets, which allows remote attackers to cause a denial of service (invalid read and use-after-free) via a crafted keyring file.(CVE-2015-1606)

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 gnupg2 packages.
