Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2018-14434)
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)
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)
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)
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)
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)
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.
