Ubuntu 16.04 ESM : Pillow vulnerabilities (USN-5227-2)

critical Nessus Plugin ID 156772

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5227-2 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)

 - 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-2021-34552)

 - 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)

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

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

Solution

Update the affected packages.
