A remote attacker could use this issue to determine the existence of a directory. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | tomcat6 | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 17.04 zesty | Not in release | | 16.10 yakkety | Not in release | | 16.04 LTS xenial | Fixed 6.0.45+dfsg-1 | | 15.10 wily | Ignored end of life | | 14.04 LTS trusty | Fixed 6.0.39-1ubuntu0.1 | | 12.04 LTS precise | Fixed 6.0.35-1ubuntu3.7 | | tomcat7 | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 17.04 zesty | Not affected | | 16.10 yakkety | Not affected | | 16.04 LTS xenial | Not affected | | 15.10 wily | Fixed 7.0.64-1ubuntu0.3 | | 14.04 LTS trusty | Fixed 7.0.52-1ubuntu0.6 | | 12.04 LTS precise | Ignored end of life | | tomcat8 | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 17.04 zesty | Not affected | | 16.10 yakkety | Not affected | | 16.04 LTS xenial | Not affected | | 15.10 wily | Ignored end of life | | 14.04 LTS trusty | Not in release | | 12.04 LTS precise | Not in release | | tomcat9 | 18.04 LTS bionic | Fixed 9.0.16-3~18.04.1 | | 17.10 artful | Not in release | | 17.04 zesty | Not in release | | 16.10 yakkety | Not in release | | 16.04 LTS xenial | Not in release | | 15.10 wily | Not in release | | 14.04 LTS trusty | Not in release | | 12.04 LTS precise | Not in release | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) * [Patch details](https://ubuntu.com/security/CVE-2015-5345?format=md#patch-details) ### Patch details For informational purposes only.
