There were several CVE bugs reported against src:netqmail.

CVE-2005-1513

Integer overflow in the stralloc_readyplus function in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large SMTP request.

CVE-2005-1514

commands.c in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long SMTP command without a space character, which causes an array to be referenced with a negative index.

CVE-2005-1515

Integer signedness error in the qmail_put and substdio_put functions in qmail, when running on 64 bit platforms with a large amount of virtual memory, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large number of SMTP RCPT TO commands.

CVE-2020-3811

qmail-verify as used in netqmail 1.06 is prone to a mail-address verification bypass vulnerability.

CVE-2020-3812

qmail-verify as used in netqmail 1.06 is prone to an information disclosure vulnerability. A local attacker can test for the existence of files and directories anywhere in the filesystem because qmail-verify runs as root and tests for the existence of files in the attacker's home directory, without dropping its privileges first.

For Debian 8 'Jessie', these problems have been fixed in version 1.06-6.2~deb8u1.

We recommend that you upgrade your netqmail packages.
