Description
This security bulletin contains information about 5 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2019-11470)
CWE-ID: CWE-400 - Resource exhaustion
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:P/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a lack of checks for insufficient image data in a file in the "ReadCINImage()" function, as defined in the "coders/cin.c" file. A remote attacker can send a specially crafted Cineon image with an incorrect claimed image size, trick a user into opening it, trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Division by zero (CVE-ID: CVE-2019-11472)
CWE-ID: CWE-369 - Divide By Zero
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:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
ReadXWDImage in coders/xwd.c in the XWD image parsing component of ImageMagick 7.0.8-41 Q16 allows attackers to cause a denial-of-service (divide-by-zero error) by crafting an XWD image file in which the header indicates neither LSB first nor MSB first.
3) Heap-based buffer overflow (CVE-ID: CVE-2019-11505)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in function WritePDBImage() in coders/pdb.c. A remote attacker can create a specially crafted image file, pass it to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Heap-based buffer overflow (CVE-ID: CVE-2019-11506)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in MAT writer within the function WriteMATLABImage of coders/mat.c, related to ExportRedQuantumType in magick/export.c. A remote attacker can create a crafted image file, pass it to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Out-of-bounds read (CVE-ID: CVE-2019-11598)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green
The vulnerability allows a remote attacker to access sensitive information or cause a denial of service (DoS) condition.
The vulnerability exists due to a boundary condition in the "WritePNMImage()" function in the "coders/pnm.c" file. A remote attacker can send a specially crafted image file (related to SetGrayscaleImage in MagickCore/quantize.c.), trick the victim into opening it, trigger out-of-bounds read error, get access to sensitive information or cause a DoS condition on the targeted system.
