## Overview

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.

## Affected

- `glibc < 2.2`

## Remediation

Upgrade past the affected range:

- `glibc 2.2`
