Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2018-20184)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to heap-based buffer overflow in the WriteTGAImage function of tga.c when processing malicious input. A remote attacker can cause the service to crash via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
2) Improper input validation (CVE-ID: CVE-2018-20189)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to an error in the ReadDIBImage function of coders/dib.c when processing malicious input in DIB reader. A remote attacker can cause the service to crash via a dib file that is crafted to appear with direct pixel values and also colormapping (which is not available beyond 8-bits/sample), and therefore lacks indexes initialization.
3) Infinite loop (CVE-ID: CVE-2018-5685)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In GraphicsMagick 1.3.27, there is an infinite loop and application hang in the ReadBMPImage function (coders/bmp.c). Remote attackers could leverage this vulnerability to cause a denial of service via an image file with a crafted bit-field mask value.
4) Divide-by-zero error (CVE-ID: CVE-2018-9018)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the ReadMNGImage function of coders/png.c due to divide-by-zero error. A remote attacker can trick the victim into opening a specially crafted mng file and cause the service to crash.
5) Out-of-bounds read (CVE-ID: CVE-2019-11006)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in the function ReadMIFFImage of coders/miff.c in MIFF reader, which allows attackers to cause a denial of service or information disclosure via an RLE packet. A remote attacker can perform a denial of service attack.
6) Heap-based buffer overflow (CVE-ID: CVE-2020-12672)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the "ReadMNGImage" in coders/png.c. A remote attacker can 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.
7) Buffer overflow (CVE-ID: CVE-2022-1270)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing MIFF files. A remote attacker can create a specially crafted MIFF file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
