Description of the vulnerability

The Apache Tomcat product offers a web service.

HTTP error pages may be customized. However, when the page content is provided by a static document instead of a servlet output, Tomcat allows to tamper with this source document.

An attacker can therefore trigger an HTTP error in Apache Tomcat, in order to corrupt the error page documents.

Description of the vulnerability

The Linux kernel includes a generic device driver for devices that comply with the MIDI interface.

However, in case of error, the function snd_usbmidi_create() frees an objet describing the MIDI interface, although this freeing is already handled by a caller function. The net result is a double free.

An attacker can therefore force a double free in the usb-audio driver of the Linux kernel, in order to trigger a denial of service, and possibly to run code.

vulnerability alert CVE-2017-1289

IBM JDK: external XML entity injection

Synthesis of the vulnerability

An attacker can transmit malicious XML data to IBM JDK, in order to read a file, scan sites, or trigger a denial of service.
Impacted products: AIX, Tivoli System Automation, Domino, Notes, RHEL, SUSE Linux Enterprise Desktop, SLES.
Severity: 2/4.
Creation date: 10/05/2017.
Identifiers: 2005058, 2005160, 2005255, 2007242, CVE-2017-1289, RHSA-2017:1220-01, RHSA-2017:1221-01, RHSA-2017:1222-01, SUSE-SU-2017:1384-1, SUSE-SU-2017:1386-1, SUSE-SU-2017:1387-1, SUSE-SU-2017:1444-1, VIGILANCE-VUL-22701.

Description of the vulnerability

XML data can contain external entities (DTD):
  <!ENTITY name SYSTEM "file">
  <!ENTITY name SYSTEM "http://server/file">
A program which reads these XML data can replace these entities by data coming from the indicated file. When the program uses XML data coming from an untrusted source, this behavior leads to:
 - content disclosure from files of the server
 - private web site scan
 - a denial of service by opening a blocking file
This feature must be disabled to process XML data coming from an untrusted source.

However, the IBM JDK parser allows external entities.

An attacker can therefore transmit malicious XML data to IBM JDK, in order to read a file, scan sites, or trigger a denial of service.
