Asterisk Project Security Advisory - AST-2021-001: Posted Feb 19, 2021; Authored by gjoseph, Ivan Poddubny | Site asterisk.org; If a registered user is tricked into dialing a malicious number that sends lots of 181 responses to Asterisk, each one will cause a 181 to be sent back to the original caller with an increasing number of entries in the ???Supported??? header. Eventually the number of entries in the header exceeds the size of the entry array and causes a crash.; tags | advisory; advisories | CVE-2020-35776; SHA-256 | 2f45006a2c9afadddcf34831d258755849dc791b989f4dce2ef9bb09888bc8d9; Download | Favorite | View
