Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities in Tomcat may lead to local file overwriting, |
| 22 |
session hijacking or information disclosure. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Tomcat is the Apache Jakarta Project's official implementation of Java |
| 28 |
Servlets and Java Server Pages. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 www-servers/tomcat < 6.0.16 *>= 5.5.26 |

>= 6.0.16 |

Description |
| 40 |
=========== |
| 41 |
|
| 42 |
The following vulnerabilities were reported: |
| 43 |
|
| 44 |
* Delian Krustev discovered that the JULI logging component does not |
| 45 |
properly enforce access restrictions, allowing web application to add |
| 46 |
or overwrite files (CVE-2007-5342). |
| 47 |
|
| 48 |
* When the native APR connector is used, Tomcat does not properly |
| 49 |
handle an empty request to the SSL port, which allows remote |
| 50 |
attackers to trigger handling of a duplicate copy of one of the |
| 51 |
recent requests (CVE-2007-6286). |
| 52 |
|
| 53 |
* If the processing or parameters is interrupted, i.e. by an |
| 54 |
exception, then it is possible for the parameters to be processed as |
| 55 |
part of later request (CVE-2008-0002). |
| 56 |
|
| 57 |
* An absolute path traversal vulnerability exists due to the way that |
| 58 |
WebDAV write requests are handled (CVE-2007-5461). |
| 59 |
|
| 60 |
* Tomcat does not properly handle double quote (") characters or %5C |
| 61 |
(encoded backslash) sequences in a cookie value, which might cause |
| 62 |
sensitive information such as session IDs to be leaked to remote |
| 63 |
attackers and enable session hijacking attacks (CVE-2007-5333). |
| 64 |
|
| 65 |
Impact |
| 66 |
====== |
| 67 |
|
| 68 |
These vulnerabilities can be exploited by: |
| 69 |
|
| 70 |
* a malicious web application to add or overwrite files with the |
| 71 |
permissions of the user running Tomcat. |
| 72 |
|
| 73 |
* a remote attacker to conduct session hijacking or disclose |
| 74 |
sensitive data. |
| 75 |
|
| 76 |
Workaround |
| 77 |
========== |
| 78 |
|
| 79 |
There is no known workaround at this time. |
| 80 |
|
| 81 |
Resolution |
| 82 |
========== |
| 83 |
|
| 84 |
All Tomcat 5.5.x users should upgrade to the latest version: |
| 85 |
|
| 86 |
# emerge --sync |
| 87 |
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-5.5.26" |
| 88 |
|
| 89 |
All Tomcat 6.0.x users should upgrade to the latest version: |
| 90 |
|
| 91 |
# emerge --sync |
| 92 |
# emerge --ask --oneshot --verbose ">=www-servers/tomcat-6.0.16" |
| 93 |
