Description
This security bulletin contains information about 11 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2017-14165)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The ReadSUNImage function in coders/sun.c in GraphicsMagick 1.3.26 has an issue where memory allocation is excessive because it depends only on a length field in a header. This may lead to remote denial of service in the MagickMalloc function in magick/memory.c.
2) Memory corruption (CVE-ID: CVE-2017-14314)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on th etarget system.
The weakness exists in the DrawImage function in magick/render.c due to off-by-one error. A remote attacker can trick the victim into opening a specially crafted file, trigger heap-based buffer over-read and cause the service to crash.
3) NULL pointer dereference (CVE-ID: CVE-2017-14504)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in coders/pnm.c in GraphicsMagick 1.3.26 does not ensure the correct number of colors for the XV 332 format, leading to a NULL Pointer Dereference. A remote attacker can perform a denial of service (DoS) attack.
4) Reachable Assertion (CVE-ID: CVE-2017-14649)
CWE-ID: CWE-617 - Reachable Assertion
CVSSv4: 6.7 [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]
The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.
ReadOneJNGImage in coders/png.c in GraphicsMagick version 1.3.26 does not properly validate JNG data, leading to a denial of service (assertion failure in magick/pixel_cache.c, and application crash).
5) Heap-based buffer overread (CVE-ID: CVE-2017-14733)
CWE-ID: CWE-126 - Buffer over-read
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to ReadRLEImage in coders/rle.c mishandles RLE headers that specify too few colors. A remote attacker can provide a specially crafted RLE document, trigger heap-based buffer over-read and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
6) NULL pointer dereference (CVE-ID: CVE-2017-14994)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted DICOM image, related to the ability of DCM_ReadNonNativeImages to yield an image list with zero frames.
7) Integer underflow (CVE-ID: CVE-2017-14997)
CWE-ID: CWE-191 - Integer underflow
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to integer underflow condition in the ReadPICTImage function, as defined in the coders/pict.c source code. A remote attacker can trick the victim into accessing a malicious image file, trigger memory allocation failure, resulting in a DoS condition on the targeted system.
8) Information disclosure (CVE-ID: CVE-2017-15277)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
ReadGIFImage in coders/gif.c in ImageMagick 7.0.6-1 and GraphicsMagick 1.3.26 leaves the palette uninitialized when processing a GIF file that has neither a global nor local palette. If the affected product is used as a library loaded into a process that operates on interesting data, this data sometimes can be leaked via the uninitialized palette.
9) Null pointer dereference (CVE-ID: CVE-2017-15930)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to an error n ReadOneJNGImage in coders/png.c. A remote attacker can transfer specially crafted JPEG scanlines, trigger null pointer dereference, related to a PixelPacket pointer and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
10) Heap-based buffer overflow (CVE-ID: CVE-2017-16352)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the "Display visual image directory" feature of the DescribeImage() function of the magick/describe.c file due to heap-based buffer overflow. A remote attacker can trick the victim into opening a specially crafted MIFF format file with the verbose flag, trigger memory corruption and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
11) Memory corruption (CVE-ID: CVE-2017-16353)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists in the DescribeImage function of the magick/describe.c file due to heap-based buffer over-read because the portion of the code containing the vulnerability is responsible for printing the IPTC Profile information contained in the image and out-of-bounds buffer dereference because certain increments are never checked. A remote attacker can trick the victim into opening a specially crafted MIFF file and gain access to potentially sensitive information.
