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.

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) download_dir, (2) cache_dir, (3) tmp_dir, and (4) pear-build-download directories, a different vulnerability than CVE-2007-2519.

Argument injection vulnerability in the ping function in Ping.php in the Net_Ping package before 2.4.5 for PEAR allows remote attackers to execute arbitrary shell commands via the host parameter. NOTE: this has also been reported as a shell metacharacter problem.

Directory traversal vulnerability in the installer in PEAR 1.0 through 1.5.3 allows user-assisted remote attackers to overwrite arbitrary files via a .. (dot dot) sequence in the (1) install-as attribute in the file element in package.xml 1.0 or the (2) as attribute in the install element in package.xml 2.0. NOTE: it could be argued that this does not cross privilege boundaries in typical installations, since the code being installed could perform the same actions.

The Next action in PEAR HTML_QuickForm_Controller 1.0.4 includes the SID in the URL even when session.use_only_cookies is configured, which allows remote attackers to obtain the SID via an HTTP Referer field and possibly other vectors.

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.
