Alert meAnalysisAI
dpkg 1.15.9 on Debian squeeze introduces support for the "C-style encoded filenames" feature without recognizing that the squeeze patch program lacks this feature, which triggers an interaction error. Rated high severity (CVSS 7.1), this vulnerability is remotely exploitable. No vendor patch available.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate and canonicalize file paths. Use chroot or sandboxing. Reject input containing path separators or '../' sequences.
