Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-11473)
The vulnerability allows a remote attacker to perform denial of service attack.
The vulnerability exists due to a boundary condition within the ReadXWDImage() function in coders/xwd.c in XWD reader. A remote attacker can create a specially crafted XWD image file, pass it to the affected application, trigger out-of-bounds read error and crash the application.
2) Incorrect calculation (CVE-ID: CVE-2019-11474)
The vulnerability allows a remote attacker to perform denial of service (DoS) attack.
The vulnerability exists due to incorrect calculation within the ReadXWDImage() function in coders/xwd.c in XWD reader. A remote attacker can create a specially crafted XWD file, pass it to the application, trigger a floating-point exception and crash the affected application.
3) Integer overflow (CVE-ID: CVE-2020-10938)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the HuffmanDecodeImage in "magick/compress.c" file. A remote attacker can trigger integer overflow and execute arbitrary code on the target system, leading to heap-based buffer overflow.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) 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.
5) 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.
6) Memory leak (CVE-ID: CVE-2019-11010)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak within the function ReadMPCImage in coders/mpc.c, which allows attackers to cause a denial of service via a crafted image file. A remote attacker can perform a denial of service attack.
7) Memory leak (CVE-ID: CVE-2019-7397)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due a memory leak in the WritePDFImage function, as defined in the coders/pdf.c source code file. A remote attacker can trick the victim into accessing a file that submits malicious input and perform denial of service attack.
8) Stack-based buffer overflow (CVE-ID: CVE-2019-11005)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing a quoted font family value within the SVGStartElement() function in coders/svg.c in SVG reader. A remote unauthenticated attacker can create a specially crafted image, pass it to the affected application, 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.
9) Path traversal (CVE-ID: CVE-2019-12921)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences within TranslateTextEx component for processing SVG images in GraphicsMagick. A remote attacker can create a specially crafted SVG file and read contents of arbitrary files on the system.
10) Memory leak (CVE-ID: CVE-2018-18544)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to memory leak in the WriteMSLImage function, as defined in the coders/msl.c source code file. A remote attacker can trick the victim into accessing a file that submits malicious input, trigger memory leak and cause the service to crash.
11) Heap-based buffer overflow (CVE-ID: CVE-2019-11008)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the WriteXWDImage() function in coders/xwd.c. A remote attacker can create a crafted XWD file, pass it to the 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.
12) Out-of-bounds read (CVE-ID: CVE-2019-11009)
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 ReadXWDImage() in coders/xwd.c, which allows attackers to cause a denial of service or information disclosure via a crafted image file. A remote attacker can perform a denial of service attack.
