Hi >From https://vinyl-cache.org/security/VSV00020.html: | A workspace buffer overflow vulnerability was found in the .upper() | and .lower() string type methods of VCL. | |This can be used as a remote denial of service (DoS) vector to make the | child process segfault or assert, and then restart. | | Effectively exploiting this vulnerability requires prior knowledge | about the VCL in use and the ability to craft a request that contains a | string that is long enough to fill the remaining workspace at the call | site while staying under the different request size limits | (http_req_size, http_req_hdr_len, ..etc). Fixed by https://code.vinyl-cache.org/vinyl-cache/vinyl-cache/commit/853d397f30753bce1587991fcf9193c63fb4d1eb in vinyl-cache-9.0.2.
