Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Debian GNU/Linux 033_-F_NO_SETSID patch for the Apache HTTP Server 1.3.34-4 does not properly disassociate httpd from a controlling tty when httpd is started interactively, which allows local users to gain privileges to that tty via a CGI program that calls the TIOCSTI ioctl.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Debian patch for Apache 1.3.34-4 (033_-F_NO_SETSID) fails to properly disassociate the Apache process from its controlling tty when started interactively. This allows local attackers to inject commands into the terminal session through the TIOCSTI ioctl via malicious CGI programs, potentially escalating privileges to the user running Apache.

MitigationUpgrade to a patched Apache version or apply the corrected Debian patch that properly calls setsid() to detach from the controlling terminal before CGI execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check installed Apache version
    Run 'dpkg -l | grep apache' or 'apache -v' to see the installed version number
    Affected if The version displayed is exactly 1.3.34-4 on Debian
  2. Confirm Apache package vendor
    Run 'dpkg -l apache' and check the package name is a Debian apache package
    Affected if The package is from Debian and version is 1.3.34-4
  3. Verify CGI module is enabled
    Check for 'AddHandler cgi-script' in httpd.conf or look for the presence of CGI directories (cgi-bin) in the Apache configuration
    Affected if CGI execution is enabled in the Apache configuration
  4. Check if Apache has a controlling terminal
    Run 'ps -p $(cat /var/run/apache.pid) -o tty=' to see if the Apache parent process has an associated tty. If a tty is listed, it was started interactively
    Affected if Apache process shows a controlling tty (output is not '?' or empty) and version is 1.3.34-4

You are affected only if running Debian Apache exactly version 1.3.34-4 with CGI enabled and the Apache process was started interactively from a terminal session.
