Description Huzaifa S. Sidhpurwala 2012-04-22 06:12:41 UTC

Using the Address Sanitizer tool, security researcher Aki Helin from OUSPG found that IDBKeyRange of indexedDB remains in the XPConnect hashtable instead of being unlinked before being destroyed. When it is destroyed, this causes a use-after-free, which is potentially exploitable.
