Description


Two vulnerabilities have been reported in Bugzilla, which can be exploited by malicious users to bypass certain security restrictions and gain knowledge of sensitive information.

1) Input passed to process_bug.cgi is not properly verified before being used. This makes it possible to change a flag on a bug report that the user does not have access to, and can be exploited to email the bug summary to the malicious user.

The vulnerability affects versions 2.17.1 through 2.18.1, and development snapshots 2.19.1 through 2.19.3.

2) A race condition when marking a bug report as private in the database can be exploited to view the report when there is a MySQL replication lag.

The vulnerability affects versions 2.17.1 and above.


Solution:
Update to version 2.18.2.
