The postinst script in the tomcat6 package before 6.0.45+dfsg-1~deb7u4 on Debian wheezy, before 6.0.35-1ubuntu3.9 on Ubuntu 12.04 LTS and on Ubuntu 14.04 LTS; the tomcat7 package before 7.0.28-4+deb7u8 on Debian wheezy, before 7.0.56-3+deb8u6 on Debian jessie, before 7.0.52-1ubuntu0.8 on Ubuntu 14.04 LTS, and on Ubuntu 12.04 LTS, 16.04 LTS, and 16.10; and the tomcat8 package before 8.0.14-1+deb8u5 on Debian jessie, before 8.0.32-1ubuntu1.3 on Ubuntu 16.04 LTS, before 8.0.37-1ubuntu0.1 on Ubuntu 16.10, and before 8.0.38-2ubuntu1 on Ubuntu 17.04 might allow local users with access to the tomcat account to obtain sensitive information or gain root privileges via a symlink attack on the Catalina localhost directory.

Security readout for executives and security teams

CVE-2016-9774 affects Debian and Ubuntu Tomcat packaging, not Tomcat upstream generally. A flawed post-install script could let someone who already has access to the tomcat account read sensitive information or escalate to root through the Catalina localhost directory. Exposure is most likely on legacy Debian wheezy/jessie and Ubuntu 12.04, 14.04, 16.04, 16.10, or 17.04 systems running affected distribution Tomcat packages. Prioritize remediation on legacy Linux servers where Tomcat hosts sensitive applications. The issue is not remotely exploitable by itself, but a web-app compromise or tomcat-account access could become full host compromise. Mitigation focus: Upgrade Debian and Ubuntu Tomcat packages to vendor-fixed versions or later.; Use Debian DSA-3738, DSA-3739, and Ubuntu USN-3177 guidance for package-specific fixes.; Remove or isolate obsolete Debian and Ubuntu releases that no longer receive routine security updates..
