What is CVE-2011-1144?

The PEAR Installer versions 1.9.2 and earlier are susceptible to a symlink vulnerability that enables local users to overwrite arbitrary files through a maliciously crafted package.xml file. This flaw arises from inadequate protections associated with critical directories such as download_dir, cache_dir, tmp_dir, and pear-build-download. Users must be aware of this vulnerability as it could lead to unauthorized access and potential system compromise.
