Security Bulletin
Summary
PowerKVM is affected by several vulnerabilities in ImageMagick. These vulnerabilities are now fixed.
Vulnerability Details
CVEID: CVE-2015-8895
DESCRIPTION: ImageMagick is vulnerable to a buffer overflow, caused by improper bounds checking by multiple integer overflows in coders/icon.c. By sending an overly long argument, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114226 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:P/A:P)
CVEID: CVE-2015-8896
DESCRIPTION: ImageMagick is vulnerable to a heap-based buffer overflow, caused by an integer truncation in coders/pict.c. By persuading a victim to open a specially crafted image file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 6.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114227 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-8897
DESCRIPTION: ImageMagick is vulnerable to a denial of service, caused by an out-of-bounds error in SpliceImage. By persuading a victim to open a specially crafted image file, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114228 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2015-8898
DESCRIPTION: ImageMagick is vulnerable to a denial of service, caused by a NULL pointer dereference in magick/constitute.c. By persuading a victim to open a specially crafted image file, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114229 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-5118
DESCRIPTION: ImageMagick and GraphicsMagick could allow a remote attacker to execute arbitrary commands on the system, caused by an error in popen() file open feature. By processing a specially-crafted filename string, an attacker could exploit this vulnerability to execute arbitrary shell commands on the system with elevated privileges.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113611 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2016-5239
DESCRIPTION: ImageMagick could allow a remote attacker to execute arbitrary commands on the system, caused by the improper validation of input prior to passing it to the gnuplot delegate functionality.. By persuading a victim to open a specially crafted image, an attacker could exploit this vulnerability to inject and execute arbitrary shell commands on the system.
CVSS Base Score: 6.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114230 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L)
CVEID: CVE-2016-5240
DESCRIPTION: ImageMagick is vulnerable to a denial of service. By persuading a victim to convert a circularly defined svg file, an attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/114231 for the current score
CVSS Environmental Score*: Undefined
