There exists a heap buffer overflow vulnerable in Abseil-cpp. The sizedconstructors, reserve(), and rehash() methods ofabsl::{flat,node}hash{set,map} did not impose an upper bound on their sizeargument. As a result, it was possible for a caller to pass a very largesize that would cause an integer overflow when computing the size of thecontainer's backing store, and a subsequent out-of-bounds memory write.Subsequent accesses to the container might also access out-of-boundsmemory. We recommend upgrading past commit5a0e2cb5e3958dd90bb8569a2766622cb74d90c1
