EulerOS Virtualization 3.0.2.0 : python-pillow (EulerOS-SA-2021-2843)

critical Nessus Plugin ID 156381

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the python-pillow package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- 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)

- 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)

- 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-2021-28677)

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-pillow packages.
