weakness alert CVE-2016-3078

PHP: integer overflow of ZipArchive-getFrom

Synthesis of the vulnerability

An attacker can create a malicious ZIP file, to generate an integer overflow in ZipArchive::getFromIndex() or ZipArchive::getFromName() of PHP, in order to trigger a denial of service, and possibly to run code.
Severity: 2/4.
Creation date: 28/04/2016.
Identifiers: 71923, CVE-2016-3078, USN-2984-1, VIGILANCE-VUL-19479.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The PHP product offers a ZipArchive module, which extracts ZIP archives.

However, if a size is too large, the getFromIndex() and getFromName() functions use an integer which overflows.

An attacker can therefore create a malicious ZIP file, to generate an integer overflow in ZipArchive::getFromIndex() or ZipArchive::getFromName() of PHP, in order to trigger a denial of service, and possibly to run code.

Quagga: assertion error via bgp_dump_obuf

Synthesis of the vulnerability

An attacker can force an assertion error in bgp_dump_obuf() of Quagga, in order to trigger a denial of service.
Severity: 1/4.
Creation date: 28/04/2016.
Identifiers: CVE-2016-4049, DLA-601-1, DSA-3654-1, FEDORA-2016-568c7ff4f6, FEDORA-2016-cae6456f63, openSUSE-SU-2016:1313-1, RHSA-2017:0794-01, USN-3102-1, VIGILANCE-VUL-19478.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The Quagga product can be configured with:
 - more than 100 neighbors
 - a regular dump such as "dump bgp routes-mrt bview.dat"

However, in this case, if large packets are received, an assertion error occurs because developers did not except this case, which stops the process.

An attacker can therefore force an assertion error in bgp_dump_obuf() of Quagga, in order to trigger a denial of service.

security weakness 19472

Linux kernel: information disclosure via TIOCSETD

Synthesis of the vulnerability

A local attacker can read a memory fragment via TIOCSETD of the Linux kernel, in order to obtain sensitive information.
Severity: 1/4.
Creation date: 27/04/2016.
Identifiers: VIGILANCE-VUL-19472.
Full Vigil@nce bulletin... (Free trial)

Description of the vulnerability

The Linux kernel implements the TIOCGETD ioctl which obtains the Line Discipline of a tty.

However, when a change is performed with a TIOCSETD, the value obtained by TIOCGETD is not always initialized.

A local attacker can therefore read a memory fragment via TIOCSETD of the Linux kernel, in order to obtain sensitive information.

cybersecurity vulnerability CVE-2016-3674

XStream: external XML entity injection

Synthesis of the vulnerability

An attacker can transmit malicious XML data to XStream, in order to read a file, scan sites, or trigger a denial of service.
Severity: 2/4.
Creation date: 27/04/2016.
Identifiers: 1985960, CVE-2016-3674, DLA-504-1, DSA-3575-1, FEDORA-2016-250042b8a6, FEDORA-2016-de909cc333, RHSA-2016:2822-01, RHSA-2016:2823-01, VIGILANCE-VUL-19471.
Full Vigil@nce bulletin... (Free trial)

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 XStream parser allows external entities.

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