Qemu: qemu-nbd crashes due to undefined I/O coroutine

An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service.

5: organization name allows XSS

A cross-site scripting (XSS) flaw was found in how an organization name is displayed in Satellite 5, before 5.8. A user able to change an organization's name could exploit this flaw to perform XSS attacks against other Satellite users.

pki-core: mock CMC authentication plugin with hardcoded secret enabled by default

It was found that a mock CMC authentication plugin with a hardcoded secret was accidentally enabled by default in the pki-core package before 10.6.4. An attacker could potentially use this flaw to bypass the regular authentication process and trick the CA server into issuing certificates.

hibernate-validator: Privilege escalation when running under the security manager

In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().

foreman: XSS in the manage organization page

foreman before version 1.16.0 is vulnerable to a stored XSS in organizations/locations assignment to hosts. Exploiting this requires a user to actively assign hosts to an organization that contains html in its name which is visible to the user prior to taking action.

openshift: XSS in log viewer for a pod

OpenShift Enterprise version 3.x is vulnerable to a stored XSS via the log viewer for pods. The flaw is due to lack of sanitation of user input, specifically terminal escape characters, and the creation of clickable links automatically when viewing the log files for a pod.

cfme: Execution of arbitrary methods through filter param

In CloudForms Management Engine (cfme) before 5.7.3 and 5.8.x before 5.8.1, it was found that privilege check is missing when invoking arbitrary methods via filtering on VMs that MiqExpression will execute that is triggerable by API users. An attacker could use this to execute actions they should not be allowed to (e.g. destroying VMs).

Ansible Tower as shipped with Red Hat CloudForms Management Engine 5 is vulnerable to CRLF Injection. It was found that X-Forwarded-For header allows internal servers to deploy other systems (using callback).

ceph: libradosstriper processes arbitrary printf placeholders in user input

In Ceph, a format string flaw was found in the way libradosstriper parses input from user. A user could crash an application or service using the libradosstriper library.

Kernel: KVM: debug exception via syscall emulation

A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.

SAT 5 XSS in the Failed Systems page

A cross-site scripting (XSS) flaw was found in how the failed action entry is processed in Red Hat Satellite before version 5.8.0. A user able to specify a failed action could exploit this flaw to perform XSS attacks against other Satellite users.

5: Failure to verify DB hostname against hostname in certificate in PostgreSQL through SSL configuration

It was found that Satellite 5 configured with SSL/TLS for the PostgreSQL backend failed to correctly validate X.509 server certificate host name fields. A man-in-the-middle attacker could use this flaw to spoof a PostgreSQL server using a specially crafted X.509 certificate.

4: ovirt-engine exposes cloud-init root password via REST API

In ovirt-engine 4.1, if a host was provisioned with cloud-init, the root password could be revealed through the REST interface.

8: Enrolling certificate without certreq field causes CA to crash

An input validation error was found in Red Hat Certificate System's handling of client provided certificates before 8.1.20-1. If the certreq field is not present in a certificate an assertion error is triggered causing a denial of service.

rpm: Following symlinks to directories when installing packages allows privilege escalation

It was found that rpm did not properly handle RPM installations when a destination path was a symbolic link to a directory, possibly changing ownership and permissions of an arbitrary directory, and RPM files being placed in an arbitrary destination. An attacker, with write access to a directory in which a subdirectory will be installed, could redirect that directory to an arbitrary location and gain root privilege.

CFME: Dialog for creating cloud volumes does not filter cloud tenants CVE-2017-7497

The dialog for creating cloud volumes (cinder provider) in CloudForms does not filter cloud tenants by user. An attacker with the ability to create storage volumes could use this to create storage volumes for any other tenant.

kernel: net/rxrpc: overflow in decoding of krb5 principal

In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer going over the end of the buffer. This could possibly lead to memory corruption and possible privilege escalation.

ansible: Security issue with lookup return not tainting the jinja2 environment

Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.

Qemu: 9p: virtfs allows guest to change filesystem attributes on host

Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System (9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing files on a shared host directory. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host.

spacewalk-backend: spacewalk-channel can be used by non-admin or disabled users for performing administrative tasks

It was found that spacewalk-channel can be used by a non-admin user or disabled users to perform administrative tasks due to an incorrect authorization check in backend/server/rhnChannel.py.
