Amazon Linux 2 : python-pillow (ALAS-2022-1786)

critical Nessus Plugin ID 160268

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python-pillow installed on the remote host is prior to 2.0.0-23.gitd1c6db8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1786 advisory.

- PIL.ImageMath.eval in Pillow before 9.0.0 allows evaluation of arbitrary expressions, such as ones that use the Python exec method. A lambda expression could also be used, (CVE-2022-22817)

- 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-2021-28676)

- path_getbbox in path.c in Pillow before 9.0.0 improperly initializes ImagePath.Path. (CVE-2022-22815)

- path_getbbox in path.c in Pillow before 9.0.0 has a buffer over-read during initialization of ImagePath.Path. (CVE-2022-22816)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update python-pillow' to update your system.
