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 8.1.1. The PDF parser allows a regular expression DoS (ReDoS) attack via a crafted PDF file because of a catastrophic backtracking regex. (CVE-2021-25292)

  • An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
    (CVE-2021-25293)

  • 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.
