Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2019-13300)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the EvaluateImages in the "MagickCore/statistic.c" file because of mishandling columns. A remote attacker can create a specially crafted file, trick the victim into opening it, 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.
2) Stack-based buffer overflow (CVE-ID: CVE-2019-13304)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WritePNMImage in the "coders/pnm.c" file because of a misplaced assignment. A remote attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Stack-based buffer overflow (CVE-ID: CVE-2019-13306)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WritePNMImage in the "coders/pnm.c" file because of "off-by-one" errors. A remote attacker can trigger stack-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-2019-13307)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the EvaluateImages in the "MagickCore/statistic.c" file because of mishandling rows. A remote attacker can create a specially crafted file, trick the victim into opening it, 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) Use-after-free (CVE-ID: CVE-2019-15140)
The vulnerability allows a remote attacker to execute arbitrary code on the target system
The vulnerability exists in "ReadImage" in the "MagickCore/constitute.c" file due to a use-after-free error when the affected software does improper memory operations. A remote attacker can trick a victim to open a specially crafted file and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Heap-based buffer overflow (CVE-ID: CVE-2019-19948)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due insufficient validation of row and column sizes in the "WriteSGIImage" function of coders/sgi.c. A remote attacker can trigger heap-based buffer overflow and cause a denial of service condition on the target system.
