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
Stack-based buffer overflow in the useragent function in useragent.c in Squid Analysis Report Generator (Sarg) 2.2.3.1 allows remote attackers to execute arbitrary code via a long Squid proxy server User-Agent header. NOTE: some of these details are obtained from third party information.

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

Stack-based buffer overflow in Sarg's useragent function when processing Squid proxy logs. The User-Agent header from proxy logs is copied into a fixed-size buffer without proper bounds checking, allowing remote attackers to overwrite stack memory and execute arbitrary code by sending unusually long User-Agent strings through the Squid proxy.

MitigationUpgrade to patched Sarg version; alternatively, implement input validation to limit User-Agent header length before Sarg processes logs, or filter/block excessively long User-Agent headers at the proxy level.

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. Identify if Sarg is installed
    Run 'sarg -v' or 'sarg --version' to display the installed Sarg version. Alternatively, check your package manager (e.g., 'dpkg -l | grep sarg' or 'rpm -qa | grep sarg').
    Affected if The installed version is 2.2.3.1 exactly.
  2. Verify the exact Sarg version
    Compare the version output from the previous step against the affected version 2.2.3.1. Sarg versions prior to 2.2.3.1 and later patched versions are not affected by this specific CVE.
    Affected if The version shown is precisely 2.2.3.1.
  3. Check if Sarg processes Squid proxy logs
    Examine the Sarg configuration file (typically /etc/sarg/sarg.conf or /etc/sarg.conf) for directives that process Squid access logs, such as 'access_log' pointing to your Squid log file.
    Affected if Sarg is configured to read Squid access logs that contain User-Agent header data.
  4. Confirm useragent processing is enabled
    Look in the Sarg configuration for settings related to user agent reporting, such as 'useragent' directive or sections that enable User-Agent field extraction from Squid logs.
    Affected if User-Agent processing or useragent reporting is explicitly enabled in the configuration.
  5. Identify if Sarg is run against live or archived Squid logs
    Review cron jobs, scripts, or automation that execute Sarg (typically via 'sarg' command) and identify which Squid log files it processes.
    Affected if Sarg is executed against Squid logs containing User-Agent headers from proxy requests.

You are affected if Sarg version 2.2.3.1 is installed AND it is configured to process Squid proxy logs with User-Agent header data enabled.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to patched Sarg version; alternatively, implement input validation to limit User-Agent header length before Sarg processes logs, or filter/block excessively long User-Agent headers at the proxy level.
