CVE-2022-41715: Memory exhaustion when compiling regular expressions in regexp/syntax
First published: Tue Oct 04 2022(Updated: )
A flaw was found in the golang package, where programs that compile regular expressions from untrusted sources are vulnerable to memory exhaustion or a denial of service. The parsed regexp representation is linear in the input size. Still, in some cases, the constant factor can be as high as 40,000, making a relatively small regexp consume larger amounts of memory. After the fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Routine use of regular expressions is unaffected.
