Stack-based buffer overflow in mod_gzip_printf for mod_gzip 1.3.26.1a and earlier, and possibly later official versions, when running in debug mode, allows remote attackers to execute arbitrary code via a long filename in a GET request with an "Accept-Encoding: gzip" header.

Security readout for executives and security teams

This is an old mod_gzip flaw where a public web request could crash or potentially take over a vulnerable server if mod_gzip debug mode is enabled. Business urgency depends on whether legacy Apache systems still run mod_gzip with debug enabled. Exposure is most likely on legacy Apache deployments using mod_gzip, especially version 1.3.26.1a or earlier, with debug mode enabled. The source bundle does not identify CPEs, distributions, or a complete affected-version range. Treat as high priority only where legacy mod_gzip is still deployed with debug mode enabled, especially on public web servers. If mod_gzip is absent or debug mode is disabled, document non-exposure and move on. Mitigation focus: Disable mod_gzip debug mode wherever present.; Remove legacy mod_gzip from internet-facing Apache servers if it is not required.; Check vendor or distribution guidance for a supported replacement or fixed package..
