Name of the Vulnerable Software and Affected Versions sqlite3 versions prior to 2.9.5

Description Redefining a SQLite function with a different arity (the number of arguments a function takes) or different text encodings using Database#create function() or Database#define function() causes the previously registered function handler to be freed while SQLite may still reference it. This leads to a use-after-free condition, which can result in an invalid memory read and a segmentation fault.

Recommendations Update to version 2.9.5 or later. As a temporary workaround, avoid defining multiple custom functions with the same name using varying numbers of arguments or encoding.
