Several functions, mostly type input functions, calculated an allocation size such that the calculation wrapped to a small positive value when arguments implied a sufficiently-large requirement. Writes past the end of the inadvertent small allocation followed shortly thereafter. Coverity identified the path_in() vulnerability; code inspection led to the rest. In passing, add check_stack_depth() to prevent stack overflow in related functions. Back-patch to 8.4 (all supported versions). The non-comment hstore changes touch code that did not exist in 8.4, so that part stops at 9.0. Noah Misch and Heikki Linnakangas, reviewed by Tom Lane. Security: CVE-2014-0064 |
