nginx vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10 - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in nginx.
Software Description: - nginx: small, powerful, scalable web/proxy server
Details:
It was discovered that nginx incorrectly handled certain DNS server responses when the resolver is enabled. A remote attacker could possibly use this issue to cause nginx to crash, resulting in a denial of service. (CVE-2016-0742)
It was discovered that nginx incorrectly handled CNAME response processing when the resolver is enabled. A remote attacker could use this issue to cause nginx to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-0746)
It was discovered that nginx incorrectly handled CNAME resolution when the resolver is enabled. A remote attacker could possibly use this issue to cause nginx to consume resources, resulting in a denial of service. (CVE-2016-0747)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.10: nginx-core 1.9.3-1ubuntu1.1 nginx-extras 1.9.3-1ubuntu1.1 nginx-full 1.9.3-1ubuntu1.1 nginx-light 1.9.3-1ubuntu1.1
