TITLE

Quagga bgpd is affected by multiple vulnerabilities

DESCRIPTION

The Quagga BGP daemon (bgpd) prior to version 1.2.3 can overrun internal BGP code-to-string conversion tables used for debug by 1 pointer value, based on input. Quagga bgpd Contains several vulnerabilities: * Buffer overflow (CWE-119) - CVE-2018-5378 (Quagga-2018-0543) * Double memory release (CWE-415) - CVE-2018-5379 (Quagga-2018-1114) * Out of bounds read (CWE-125) - CVE-2018-5380 (Quagga-2018-1550) * Improper handling of incorrect syntactic constructs (CWE-228) - CVE-2018-5381 (Quagga-2018-1975) Detail is <a href="https://savannah.nongnu.org/forum/forum.php?forum_id=9095"target="blank"> Information provided by the developer </a> Please refer to.The expected impact depends on each vulnerability, but remote code execution, information leakage, service operation interruption by a remote third party (DoS) An attack could be made. Quagga is prone to multiple denial of service vulnerabilities. Attackers can exploit these issues to crash the affected application, denying service to legitimate users. A configured peer can take advantage of this flaw to cause a denial of service (bgpd daemon not responding to any other events; BGP sessions will drop and not be reestablished; unresponsive CLI interface). https://www.quagga.net/security/Quagga-2018-1975.txt For the oldstable distribution (jessie), these problems have been fixed in version 0.99.23.1-1+deb8u5. For the stable distribution (stretch), these problems have been fixed in version 1.1.1-3+deb9u2. We recommend that you upgrade your quagga packages.

Software Description: - quagga: BGP/OSPF/RIP routing daemon Details: It was discovered that a double-free vulnerability existed in the Quagga BGP daemon when processing certain forms of UPDATE message. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2018-5379) It was discovered that the Quagga BGP daemon did not properly bounds check the data sent with a NOTIFY to a peer. An attacker could use this to expose sensitive information or possibly cause a denial of service. This issue only affected Ubuntu 17.10. An attacker in control of a configured peer could use this to possibly expose sensitive information or possibly cause a denial of service. (CVE-2018-5380) It was discovered that the Quagga BGP daemon in some configurations did not properly handle invalid OPEN messages. An attacker in control of a configured peer could use this to cause a denial of service (infinite loop). (CVE-2018-5381) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: quagga 1.1.1-3ubuntu0.2 quagga-bgpd 1.1.1-3ubuntu0.2 Ubuntu 16.04 LTS: quagga 0.99.24.1-2ubuntu1.4 Ubuntu 14.04 LTS: quagga 0.99.22.4-3ubuntu1.5 After a standard system update you need to restart Quagga to make all the necessary changes.
