The default configuration of logrotate on Debian GNU/Linux uses root privileges to process files in directories that permit non-root write access, which allows local users to conduct symlink and hard link attacks by leveraging logrotate's lack of support for untrusted directories, as demonstrated by /var/log/postgresql/.

Security readout for executives and security teams

CVE-2011-1548 concerns Debian's default logrotate behavior. Logrotate could process logs as root inside directories where non-root users could write, creating a local link-attack risk. This is not described as remotely exploitable, and the supplied sources do not show active exploitation or a named patch. Exposure is most likely on older Debian systems using the affected default logrotate configuration with service log directories writable by non-root users. The bundle does not identify exact Debian versions, packages, or downstream products. Treat this as a legacy local privilege-risk item. It is not an internet-facing emergency from the supplied evidence, but it matters on multi-user Debian systems or servers where services can write into log directories handled by root. Mitigation focus: Check Debian and logrotate vendor guidance for supported updates or configuration changes.; Ensure root-rotated log directories are not writable by non-root users.; Review service log directories, including PostgreSQL-style paths, for unsafe ownership or permissions..
