Summary

The dpkg-source tool in dpkg versions 1.3.0 through 1.18.23 is susceptible to directory traversal attacks due to its ability to accept non-GNU patch programs and lack of protective mechanisms for blank-indented diff hunks. This flaw enables remote attackers to craft specific Debian source packages, potentially compromising the target system's file structure. An exploit could facilitate unauthorized access to sensitive files, highlighting the critical need for updated protections against such vulnerabilities.
