Debian LTS: Security Advisory for pillow (DLA-2716-1)

Published: 2021-07-23 03:00:13
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Summary:
The remote host is missing an update for the 'pillow' Linux Distribution Package(s) announced via the DLA-2716-1 advisory.

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

Technical Details:
Several vulnerabilities have been discovered in pillow (Python Imaging Library - PIL). Affected binary Linux Distribution Packages: python-imaging python-pil-dbg python-pil-doc python-pil.imagetk-dbg python-pil.imagetk python-pil python3-pil-dbg python3-pil.imagetk-dbg python3-pil.imagetk python3-pil CVE-2020-35653 Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c. CVE-2021-25290 An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an invalid size. CVE-2021-28676 An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load. CVE-2021-28677 An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could use this to perform a DoS of Pillow in the open phase, before an image was accepted for opening. CVE-2021-34552 Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.

Affected Versions:
'pillow' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 9 stretch, these problems have been fixed in version 4.0.0-4+deb9u3. We recommend that you upgrade your pillow Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

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".
