Debian dla-3768 : python-pil - security update

critical Nessus Plugin ID 192475


The remote Debian host is missing one or more security-related updates.


The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3768 advisory.

- The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function. (CVE-2021-23437)

- 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 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory.
This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument. (CVE-2023-44271)

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


Upgrade the python-pil packages.
