Comment 6 Vasyl Kaigorodov 2015-04-28 13:34:33 UTC 
Common Vulnerabilities and Exposures assigned an identifier CVE-2015-3414 to
the following vulnerability:

Name: CVE-2015-3414
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-3414
Assigned: 20150424
Reference: https://www.sqlite.org/src/info/eddc05e7bb31fae74daa86e0504a3478b99fa0f2

SQLite before 3.8.9 does not properly implement the dequoting of
collation-sequence names, which allows context-dependent attackers to
cause a denial of service (uninitialized memory access and application
crash) or possibly have unspecified other impact via a crafted COLLATE
clause, as demonstrated by COLLATE"""""""" at the end of a SELECT
statement.
Comment 9 Siddharth Sharma 2015-07-03 09:03:04 UTC 
RHEL 5 and 6 are *NOT affected by this flaw as the code affected by this CVE is not present in the sqlite package shipped for these products.
