2022-11-01Fix CVE-2022-3786 in punycode decoder.Pauli
Fixed the ossl_a2ulabel() function which also contained a potential buffer overflow, albeit without control of the contents. This overflow could result in a crash (causing a denial of service). The function also did not NUL-terminate the output in some cases. The two issues fixed here were dentified and reported by Viktor Dukhovni while researching CVE-2022-3602.
