CVE-2013-7135: The Proc::Daemon module 0.14 for Perl uses world-writable permissions for a file that stores a process ID,...

Security readout for executives and security teams

Proc::Daemon 0.14, a Perl module used to daemonize processes, created a process ID file with permissions that let local users modify it. That can interfere with process management. The public record does not define the exact impact, severity score, or affected downstream applications. Exposure is most likely in legacy Perl services using Proc::Daemon 0.14, especially on shared Unix/Linux systems with untrusted local users. Network-only exposure is not supported by the sources. Systems that do not use this module or do not allow local shell access are less likely exposed. Treat as a targeted hygiene issue for legacy Perl systems, not an emergency internet-wide risk. Prioritize shared servers, production hosts with local users, and packaged systems covered by vendor advisories. Mitigation focus: Identify applications depending on Proc::Daemon 0.14.; Check CPAN, OS vendor, or package maintainer guidance for fixed versions.; Apply relevant distribution security updates where available..
