Juniper Networks Patches Vulnerabilities in Contrail Networking, Junos OS

Juniper Networks this week announced the release of patches for more than 30 vulnerabilities across its portfolio, including severe flaws in Contrail Networking and Junos OS.

Two advisories describing a total of 13 security holes in the Contrail Networking software-defined networking (SDN) solution were published this week, with seven of the bugs carrying a CVSS score above 9.0.

The first of the advisories covers ten issues impacting Contrail Networking releases prior to 2011.L4. Five of these security defects are rated critical and all of them were identified last year.

The most severe of these are two buffer overflow vulnerabilities in Pillow (CVE-2021-25289 and CVE-2021-34552) and a heap overflow in Apache HTTP Server (CVE-2021-26691). All three have a CVSS score of 9.8.

With a CVSS score of 9.4, the other two impact the nginx resolver (CVE-2021-23017) and the xmlhttprequest-ssl package (CVE-2021-31597).

The second advisory describes two critical issues in Contrail Networking prior to version 21.3. These include a remote code execution bug in Git for Visual Studio (CVE-2019-1349) and a denial of service (DoS) in the pcre_compile function in pcre_compile.c in PCRE (CVE-2015-8391).

This week, Juniper Networks also announced patches for 14 vulnerabilities in Junos OS and Junos OS Evolved, including 10 issues rated “high severity,” which could lead to code execution or DoS, in certain conditions.

Juniper Networks says it is not aware of any of these Junos OS vulnerabilities being exploited in attacks, but encourages customers to update to a patched release as soon as possible.

The US Cybersecurity and Infrastructure Security Agency (CISA) too is encouraging users and administrators to review the advisories and apply the necessary fixes immediately.

“An attacker could exploit some of these vulnerabilities to take control of an affected system,” CISA warns.
