Description
The installer in PEAR 1.9.2 and earlier allows local users to overwrite arbitrary files via a symlink attack on the package.xml file, related to the (1) download_dir, (2) cache_dir, (3) tmp_dir, and (4) pear-build-download directories. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1072.
