CVE-2010-2253

perl-libwww-perl: multiple HTTP client download filename vulnerability [OCERT 2010-001]

lwp-download in libwww-perl before 5.835 does not reject downloads to filenames that begin with a . (dot) character, which allows remote servers to create or overwrite files via (1) a 3xx redirect to a URL with a crafted filename or (2) a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a dotfile in a home directory.

CVE-2011-0633

perl-libwww-perl: no hostname check against SSL certificate name by default

The Net::HTTPS module in libwww-perl (LWP) before 6.00, as used in WWW::Mechanize, LWP::UserAgent, and other products, when running in environments that do not set the If-SSL-Cert-Subject header, does not enable full validation of SSL certificates by default, which allows remote attackers to spoof servers via man-in-the-middle (MITM) attacks involving hostnames that are not properly validated. NOTE: it could be argued that this is a design limitation of the Net::HTTPS API, and separate implementations should be independently assigned CVE identifiers for not working around this limitation. However, because this API was modified within LWP, a single CVE identifier has been assigned.
