Summary

Several vulnerabilities in PHP affect IBM Security Virtual Server Protection 
for VMware.

Vulnerability Details

CVEID: CVE-2014-9709

DESCRIPTION: gd-libgd is vulnerable to a stack-based buffer overflow, caused 
by improper bounds checking by gd_gif_in.c. By sending a specially-crafted GIF
file, a remote attacker could overflow a buffer and execute arbitrary code on
the system or cause the server to crash.

CVSS Base Score: 6.8

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/101757 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-0232

DESCRIPTION: PHP could allow a remote attacker to execute arbitrary code on 
the system, caused by an error in the exif_process_unicode function. An 
attacker could exploit this vulnerability using specially-crafted EXIF data to
execute arbitrary code on the system.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/100570 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-2787

DESCRIPTION: PHP could allow a remote attacker to execute arbitrary code on 
the system, caused by an use-after-free error in the unserialize() function. 
By abusing the defined __wakeup() magic method, an attacker could exploit this
vulnerability to execute arbitrary PHP code on the system.

CVSS Base Score: 6.8

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-3411

DESCRIPTION: PHP could allow a remote attacker to bypass security 
restrictions, caused by the failure to properly handle file names containing a
NULL character. An attacker could exploit this vulnerability using a path name
containing null characters to bypass file system access restrictions.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/104108 for the current 
score

CVEID: CVE-2015-3412

DESCRIPTION: PHP could allow a remote attacker to bypass security 
restrictions, caused by the failure to properly handle file names containing a
NULL character. An attacker could exploit this vulnerability using a path name
containing null characters to bypass file system access restrictions.

CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-4022

DESCRIPTION: PHP is vulnerable to a heap-based buffer overflow, caused by 
improper bounds checking by the FTP extension in the parsing of file listings.
By sending an overly long argument, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.

CVSS Base Score: 7.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/103518 for the current

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-4024

DESCRIPTION: PHP is vulnerable to a denial of service, caused by an error when
parsing malicious requests. By sending a specially-crafted HTTP POST request,
an attacker could exploit this vulnerability to consume all available CPU 
resources.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/103516 for the current

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-4026

DESCRIPTION: PHP could allow a remote attacker to bypass security 
restrictions, caused by the acceptance of a NULL value in a path by the 
pcnt_exec() function. By sending a specially-crafted value, an attacker could
exploit this vulnerability to bypass security controls.
