Description Martin Prpič 2016-02-09 05:33:06 EST
It is possible to craft SQLite databases that, when opened by an application expecting a specific SQL schema, could cause arbitrary code execution.

The issue is in the handling of the fts3_tokenizer function:


Yum might be affected, but due to the use of HTTPS in RHEL, and in Fedora, the digest from the mirror list service should
protect clients.

The issue does not appear to be fixed upstream yet:

Comment 5 Martin Prpič 2016-02-18 04:28:17 EST
This issue has been fixed in the 3.11.0 release of sqlite:


"Because of continuing security concerns, the two-argument version of the seldom-used and little-known fts3_tokenizer() function is disabled unless SQLite is compiled with the SQLITE_ENABLE_FTS3_TOKENIZER."
Comment 6 Stefan Cornelius 2016-06-14 06:02:49 EDT

This issue did not affect the versions of sqlite as shipped with Red Hat Enterprise Linux 5 and 6.
