EulerOS 2.0 SP2 : glibc (EulerOS-SA-2019-1844)

medium Nessus Plugin ID 128896

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - Stack-based buffer overflow in the glob implementation in GNU C Library (aka glibc) before 2.24, when GLOB_ALTDIRFUNC is used, allows context-dependent attackers to cause a denial of service (crash) via a long name.(CVE-2016-1234)

 - The DNS stub resolver in the GNU C Library (aka glibc or libc6) before version 2.26, when EDNS support is enabled, will solicit large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation.(CVE-2017-12132)

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 glibc packages.
