AZL-49027 CVE-2024-23185 affecting package dovecot 2.3.20-1

Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "fullvalue" buffer out of the smaller chunks. The fullvalue buffer has no si...

CVE-2024-23184

Having a large number of address headers From, To, Cc, Bcc, etc. becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors...
