A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

An integer overflow was found in the Linux kernel's vmwgfx driver. This flaw allows a local, unprivileged attacker with access to either /dev/dri/card0 or /dev/dri/rendererD128, and able to issue an ioctl() on the resulting file descriptor to crash the system, causing a denial of service.

The host is installed with kernel through 3.18.2 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to properly handle keyctl commands that trigger access to a key structure member during garbage collection of a key. Successful exploitation allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified oth ...

The host is installed with kernel on Red Hat Enterprise Linux 7 and is prone to a stack-based buffer overflow vulnerability. A flaw is present in the application, which fails to properly handle a crafted microcode header. Successful exploitation could allow attackers to escalate privileges on the affected system.

The host is installed with kernel on RHEL 6, or 7 and is prone to a privilege escalation vulnerability. A flaw is present in the application, which fails to properly handle IRET faults in processing NMIs that occurred during userspace execution. Successful exploitation could allow attackers to gain privileges.

A flaw was found in OpenSSL. An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function, most likely leading to an application crash. This function can be called on public keys supplied from untrusted sources, which could allow an attacker to cause a denial of service.

A NULL pointer vulnerability was found in OpenSSL, which can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available, the digest initialization will fail. There is a missing check for the return value from the initial ...

The host is installed with RHEL 6 or 7 and is prone to an out-of-bounds heap read vulnerability. A flaw is present in the application, which fails to handle a malformed input document. Successful exploitation could allow attackers to execute arbitrary code or crash the service.

The host is installed with Linux kernel through 3.17.2 and is prone to a denial of service vulnerability. A flaw is present in the application, which miscalculates the number of pages during the handling of a mapping failure. Successful exploitation allows guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact.

The host is installed with Linux kernel before 3.16.3 and is prone to a denial of service vulnerability. A flaw is present in the application, which does not properly implement garbage collection. Successful exploitation allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact.
