Not exploitable, just DoS. Use CVE-2015-4054. issues/42 says "we're suffering from a segmentation fault every now and then on CentOS6 x86_64 with pgbouncer 1.5.4. The instance is dying" and lists 5 different PIDs. As far as we can tell, this means that each segmentation fault caused a complete pgbouncer outage, and pgbouncer was then restarted manually or with a third-party monitoring program. We don't think the report means that an "instance" crashed and pgbouncer itself continued with no outage (that type of issue is often outside the scope of CVE, if it means that a single client is essentially conducting a DoS attack against its own service). Also, as far as we can tell, an outage doesn't depend on whether -d was used. - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJVXyrFAAoJEKllVAevmvms/qEH/08RKvuaPUXOdG1oqRQXSBuv yu8MVbaDuRcsMv9LoKyo2arMD7gsTstaRkrf5yZU8WDtbE1R5vqIjzMl7Bt6nzSY aBBCxFjqlR4tuEbuZTmSBcWTHvVtkoFSwr3pegqUzEKL/3e0xL1/DxQtdRseXAIv Kzvsatm0lOCxI+TIjMWp7OHgb8rgp4DLXtCs2zr13uUph6Ff8rU0Gq1vx9lM8GMD +7FVHAYXUP98w38tMstWojXriKdXN5oJQ+K+W8QinQsALeNduTI7EqUvhkE1aqCi MTPGVqkKKxsynQJsoPzdjQvWEqYGVDDN3icRNY9Ej4ZVUuKETFHhN3Kn4dp2Oso= =DLec -----END PGP SIGNATURE-----
