Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2012-1571)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

file before 5.11 and libmagic allow remote attackers to cause a denial of service (crash) via a crafted Composite Document File (CDF) file that triggers (1) an out-of-bounds read or (2) an invalid pointer dereference.


2) NULL pointer dereference (CVE-ID: CVE-2014-2497)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted color table in an XPM file.


3) Integer overflow (CVE-ID: CVE-2014-3587)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to integer overflow in the cdf_read_property_info function in cdf.c in file through 5.19, as used in the Fileinfo component in PHP before 5.4.32 and 5.5.x before 5.5.16. A remote attacker can trigger memory corruption via a crafted CDF fileand cause the service to crash.

4) Input validation error (CVE-ID: CVE-2014-5120)

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

gd_ctx.c in the GD component in PHP 5.4.x before 5.4.32 and 5.5.x before 5.5.16 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to overwrite arbitrary files via crafted input to an application that calls the (1) imagegd, (2) imagegd2, (3) imagegif, (4) imagejpeg, (5) imagepng, (6) imagewbmp, or (7) imagewebp function.
