USN-1637-1: Tomcat vulnerabilities

21 November 2012

Several security issues were fixed in Apache Tomcat.




It was discovered that the Apache Tomcat HTTP NIO connector incorrectly
handled header data. A remote attacker could cause a denial of service by
sending requests with a large amount of header data. (CVE-2012-2733)

It was discovered that Apache Tomcat incorrectly handled DIGEST
authentication. A remote attacker could possibly use these flaws to perform
a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886,

Update instructions
