Unspecified vulnerability in PEAR installer 1.4.2 and earlier allows user-assisted attackers to execute arbitrary code via a crafted package that can execute code when the pear command is executed or when the Web/Gtk frontend is loaded.

The installer in PEAR before 1.9.2 allows local users to overwrite arbitrary files via a symlink attack on the package.xml file, related to the (1) downloaddir, (2) cachedir, (3) tmpdir, and (4) pear-build-download directories, a different vulnerability than CVE-2007-2519.
