The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3444-1 advisory.

  - A flaw was found in RPM's hdrblobInit() in lib/header.c. This flaw allows an attacker who can modify the     rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability is to system     availability. (CVE-2021-20266)

  - A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an     attacker who can convince a victim to install a seemingly verifiable package, whose signature header was     modified, to cause RPM database corruption and execute code. The highest threat from this vulnerability is     to data integrity, confidentiality, and system availability. (CVE-2021-20271)

  - A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can     convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM     database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects     RPM versions before 4.17.0-alpha. (CVE-2021-3421)
