Redhat: Security Vulnerabilities
In etcd before versions 3.3.23 and 3.4.10, the etcd gateway is a simple TCP proxy to allow for basic service discovery and access. However, it is possible to include the gateway address as an endpoint. This results in a denial of service, since the endpoint can become stuck in a loop of requesting itself until there are no more available file descriptors to accept connections on the gateway.

In ectd before versions 3.4.10 and 3.3.23, gateway TLS authentication is only applied to endpoints detected in DNS SRV records. When starting a gateway, TLS authentication will only be attempted on endpoints identified in DNS SRV records for a given domain, which occurs in the discoverEndpoints function. No authentication is performed against endpoints provided in the --endpoints flag. This has been fixed in versions 3.4.10 and 3.3.23 with improved documentation and deprecation of the functionality.

etcd before versions 3.3.23 and 3.4.10 does not perform any password length validation, which allows for very short passwords, such as those with a length of one. This may allow an attacker to guess or brute-force users' passwords with little computational effort.

It was found that the AMQ Online console is vulnerable to a Cross-Site Request Forgery (CSRF) which is exploitable in cases where preflight checks are not instigated or bypassed. For example authorised users using an older browser with Adobe Flash are vulnerable when targeted by an attacker. This flaw affects all versions of AMQ-Online prior to 1.5.2 and Enmasse versions 0.31.0-rc1 up until but not including 0.32.2.

There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow.

There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow.

A flaw was found in the nova_libvirt container provided by the Red Hat OpenStack Platform 16, where it does not have SELinux enabled. This flaw causes sVirt, an important isolation mechanism, to be disabled for all running virtual machines.

A data exposure flaw was found in Tower, where sensitive data was revealed from the HTTP return error codes. This flaw allows an unauthenticated, remote attacker to retrieve pages from the default organization and verify existing usernames. The highest threat from this vulnerability is to data confidentiality.

A flaw was found in kubevirt 0.29 and earlier. Virtual Machine Instances (VMIs) can be used to gain access to the host's filesystem. Successful exploitation allows an attacker to assume the privileges of the VM process on the host system. In worst-case scenarios an attacker can read and modify any file on the system where the VMI is running. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
