Description
This security bulletin contains information about 6 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2018-14434)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
ImageMagick 7.0.8-4 has a memory leak for a colormap in WriteMPCImage in coders/mpc.c.
2) Memory leak (CVE-ID: CVE-2018-14435)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to memory leak in DecodeImage in coders/pcd.c. A remote attacker can trick the victim into opening a specially crafted input, trigger memory corruption and cause the service to crash.
3) Memory leak (CVE-ID: CVE-2018-14436)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within ReadMIFFImage in coders/miff.c. A remote attacker can perform a denial of service attack.
4) Memory leak (CVE-ID: CVE-2018-14437)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within parse8BIM in coders/meta.c. A remote attacker can perform a denial of service attack.
5) Information disclosure (CVE-ID: CVE-2018-16323)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
ReadXBMImage in coders/xbm.c in ImageMagick before 7.0.8-9 leaves data uninitialized when processing an XBM file that has a negative pixel value. If the affected code is used as a library loaded into a process that includes sensitive information, that information sometimes can be leaked via the image data.
6) Null pointer dereference (CVE-ID: CVE-2018-16329)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the GetMagickProperty function of ImageMagick due to boundary error when processing malicious input. A remote attacker can trick the victim into accessing an image file that submits malicious input, trigger a NULL pointer dereference condition in the GetMagickProperty function as defined in the MagickCore/log.c source code file and cause the service to crash.
