manual/search.texi in the GNU C Library (aka glibc) before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree’s root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999.

Weakness

The software does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
