Description
Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected.
Affected products
- Apache HTTP Server: before 2.4.54 — fixed in 2.4.54
- Fedoraproject Fedora: 35, 36
- Clustered Data ONTAP: all versions
How to fix
Upgrade to a fixed version: Apache HTTP Server 2.4.54. Check the vendor advisory for mitigations.
