Ubuntu 20.04 LTS : netqmail vulnerabilities (USN-4556-1)

critical Nessus Plugin ID 141054

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4556-1 advisory.

 - 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-2005-1513)

 - 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-2005-1514)

 - 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-2005-1515)

 - qmail-verify as used in netqmail 1.06 is prone to a mail-address verification bypass vulnerability.
 (CVE-2020-3811)

 - 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. (CVE-2020-3812)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected qmail and / or qmail-uids-gids packages.
