Description

According to the versions of the python-pillow package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  • A flaw was found in python-pillow. In TiffDecode.c, there is a negative-offset memcpy with an invalid size which could lead to a system crash.(CVE-2021-25290)

  • A flaw was found in python-pillow. PsdImagePlugin.PsdImageFile does not sanity check the number of input layers with regard to the size of the data block which could lead to a denial-of-service.(CVE-2021-28675)

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.
