Debian LTS: Security Advisory for imagemagick (DLA-2523-1)

Published: 2021-01-13 04:00:30
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

The remote host is missing an update for the 'imagemagick' Linux Distribution Package(s) announced via the DLA-2523-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2017-14528 The TIFFSetProfiles function in coders/tiff.c has incorrect expectations about whether LibTIFF TIFFGetField return values imply that data validation has occurred, which allows remote attackers to cause a denial of service (use-after-free after an invalid call to TIFFSetField, and application crash) via a crafted file. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type `unsigned char` and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In `GammaImage()` of /MagickCore/enhance.c, depending on the `gamma` value, it's possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
