Candidate: CVE-2018-9860 PublicDate: 2018-04-12 05:29:00 UTC References: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-9860 https://github.com/randombit/botan/commit/ec222c99719c396a1f4756b2ca345dbbfbeb5ed5 Description: An issue was discovered in Botan 1.11.32 through 2.x before 2.6.0. An off-by-one error when processing malformed TLS-CBC ciphertext could cause the receiving side to include in the HMAC computation exactly 64K bytes of data following the record buffer, aka an over-read. The MAC comparison will subsequently fail and the connection will be closed. This could be used for denial of service. No information leak occurs.
