Dawid Golunski from LegalHackers discovered that PHP Swift Mailer, a
mailing solution for PHP, did not correctly validate user input. This
allowed a remote attacker to execute arbitrary code by passing
specially formatted email addresses in specific email headers.

Multiple vulnerabilities in OpenJPEG, a JPEG 2000 image compression /
decompression library, may result in denial of service or the execution
of arbitrary code if a malformed JPEG 2000 file is processed.

It was discovered that mapserver, a CGI-based framework for Internet
map services, was vulnerable to a stack-based overflow. This issue
allowed a remote user to crash the service, or potentially execute
arbitrary code.

Several issues have been discovered in the MySQL database server. The
vulnerabilities are addressed by upgrading MySQL to the new upstream
version 5.5.54, which includes additional changes, such as performance
improvements, bug fixes, new features, and possibly incompatible

Several programming errors in the wrestool tool of icoutils, a suite
of tools to create and extract MS Windows icons and cursors, allow

Florian Heinz and Martin Kluge reported that pdns-recursor, a recursive
DNS server, parses all records present in a query regardless of whether
they are needed or even legitimate, allowing a remote, unauthenticated
attacker to cause an abnormal CPU usage load on the pdns server,
resulting in a partial denial of service if the system becomes
overloaded.

Multiple vulnerabilities have been discovered in pdns, an authoritative
DNS server. The Common Vulnerabilities and Exposures project identifies
the following problems:

Multiple vulnerabilities have been discovered in the libtiff library
and the included tools tiff2rgba, rgb2ycbcr, tiffcp, tiffcrop, tiff2pdf
and tiffsplit, which may result in denial of service, memory disclosure
or the execution of arbitrary code.

It was discovered that RabbitMQ, an implementation of the AMQP
protocol, didn’t correctly validate MQTT (MQ Telemetry Transport)
connection authentication. This allowed anyone to login to an existing
user account without having to provide a password.

Multiple vulnerabilities have been found in the Ikiwiki wiki compiler:
