CVE-2010-2253: lwp-download in libwww-perl before 5.835 does not reject downloads to filenames that begin with a .

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.

Security readout for executives and security teams

CVE-2010-2253 affects the lwp-download utility in libwww-perl before 5.835. A malicious server could cause it to save a hidden dotfile, potentially overwriting user configuration files. In some environments, that overwrite could later lead to code execution. Exposure is most likely on systems or scripts using libwww-perl lwp-download before 5.835 to fetch content from untrusted or attacker-controlled URLs. Linux distributions shipped advisories, including Ubuntu and Fedora. Treat as a targeted hygiene issue, not an emergency. Prioritize internet-facing automation, build systems, and legacy hosts that fetch from external sources using old Perl tooling. Mitigation focus: Upgrade libwww-perl to version 5.835 or later.; Apply relevant operating system vendor updates.; Avoid lwp-download for untrusted URLs until patched..
