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 Temporal Score: See

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
score
CVSS Environmental Score*: Undefined
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 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.
