Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system. (CVE-2016-0758, Important) Red Hat would like to thank Philip Pettersson of Samsung for reporting this issue. Bug Fix(es) : * Under certain conditions, the migration threads could race with the CPU hotplug, which could cause a deadlock. A set of patches has been provided to fix this bug, and the deadlock no longer occurs in the system. (BZ# 1299338) * A bug in the code that cleans up revoked delegations could previously cause a soft lockup in the NFS server. This patch fixes the underlying source code, so the lockup no longer occurs. (BZ#1311582) * The second attempt to reload Common Application Programming Interface (CAPI) devices on the little-endian variant of IBM Power Systems previously failed. The provided set of patches fixes this bug, and reloading works as intended. (BZ#1312396) * Due to inconsistencies in page size of IOMMU, the NVMe device, and the kernel, the BUG_ON signal previously occurred in the nvme_setup_prps() function, leading to the system crash while setting up the DMA transfer. The provided patch sets the default NVMe page size to 4k, thus preventing the system crash. (BZ#1312399) * Previously, on a system using the Infiniband mlx5 driver used for the SRP stack, a hard lockup previously occurred after the kernel exceeded time with lock held with interrupts blocked. As a consequence, the system panicked. This update fixes this bug, and the system no longer panics in this situation. (BZ#1313814) * On the little-endian variant of IBM Power Systems, the kernel previously crashed in the bitmap_weight() function while running the memory affinity script. The provided patch fortifies the topology setup and prevents sd-> child from being set to NULL when it is already NULL. As a result, the memory affinity script runs successfully. (BZ#1316158) * When a KVM guest wrote random values to the special-purpose registers (SPR) Instruction Authority Mask Register (IAMR), the guest and the corresponding QEMU process previously hung. This update adds the code which sets SPRs to a suitable neutral value on guest exit, thus fixing this bug. (BZ#1316636) * Under heavy iSCSI traffic load, the system previously panicked due to a race in the locking code leading to a list corruption. This update fixes this bug, and the system no longer panics in this situation. (BZ#1316812) * During SCSI exception handling (triggered by some irregularities), the driver could previously use an already retired SCSI command. As a consequence, a kernel panic or data corruption occurred. The provided patches fix this bug, and exception handling now proceeds successfully. (BZ #1316820) * When the previously opened /dev/tty, which pointed to a pseudo terminal (pty) pair, was the last file closed, a kernel crash could previously occur. The underlying source code has been fixed, preventing this bug. (BZ# 1320297) * Previously, when using VPLEX and FCoE via the bnx2fc driver, different degrees of data corruption occurred.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system. (CVE-2016-0758, Important) Red Hat would like to thank Philip Pettersson of Samsung for reporting this issue. Bug Fix(es) : * Under certain conditions, the migration threads could race with the CPU hotplug, which could cause a deadlock. A set of patches has been provided to fix this bug, and the deadlock no longer occurs in the system. (BZ# 1299338) * A bug in the code that cleans up revoked delegations could previously cause a soft lockup in the NFS server. This patch fixes the underlying source code, so the lockup no longer occurs. (BZ#1311582) * The second attempt to reload Common Application Programming Interface (CAPI) devices on the little-endian variant of IBM Power Systems previously failed. The provided set of patches fixes this bug, and reloading works as intended. (BZ#1312396) * Due to inconsistencies in page size of IOMMU, the NVMe device, and the kernel, the BUG_ON signal previously occurred in the nvme_setup_prps() function, leading to the system crash while setting up the DMA transfer. The provided patch sets the default NVMe page size to 4k, thus preventing the system crash. (BZ#1312399) * Previously, on a system using the Infiniband mlx5 driver used for the SRP stack, a hard lockup previously occurred after the kernel exceeded time with lock held with interrupts blocked. As a consequence, the system panicked. This update fixes this bug, and the system no longer panics in this situation. (BZ#1313814) * On the little-endian variant of IBM Power Systems, the kernel previously crashed in the bitmap_weight() function while running the memory affinity script. The provided patch fortifies the topology setup and prevents sd-> child from being set to NULL when it is already NULL. As a result, the memory affinity script runs successfully. (BZ#1316158) * When a KVM guest wrote random values to the special-purpose registers (SPR) Instruction Authority Mask Register (IAMR), the guest and the corresponding QEMU process previously hung. This update adds the code which sets SPRs to a suitable neutral value on guest exit, thus fixing this bug. (BZ#1316636) * Under heavy iSCSI traffic load, the system previously panicked due to a race in the locking code leading to a list corruption. This update fixes this bug, and the system no longer panics in this situation. (BZ#1316812) * During SCSI exception handling (triggered by some irregularities), the driver could previously use an already retired SCSI command. As a consequence, a kernel panic or data corruption occurred. The provided patches fix this bug, and exception handling now proceeds successfully. (BZ #1316820) * When the previously opened /dev/tty, which pointed to a pseudo terminal (pty) pair, was the last file closed, a kernel crash could previously occur.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system. (CVE-2016-0758, Important) Red Hat would like to thank Philip Pettersson of Samsung for reporting this issue. Bug Fix(es) : * Under certain conditions, the migration threads could race with the CPU hotplug, which could cause a deadlock. A set of patches has been provided to fix this bug, and the deadlock no longer occurs in the system. (BZ# 1299338) * A bug in the code that cleans up revoked delegations could previously cause a soft lockup in the NFS server. This patch fixes the underlying source code, so the lockup no longer occurs. (BZ#1311582) * The second attempt to reload Common Application Programming Interface (CAPI) devices on the little-endian variant of IBM Power Systems previously failed. The provided set of patches fixes this bug, and reloading works as intended. (BZ#1312396) * Due to inconsistencies in page size of IOMMU, the NVMe device, and the kernel, the BUG_ON signal previously occurred in the nvme_setup_prps() function, leading to the system crash while setting up the DMA transfer. The provided patch sets the default NVMe page size to 4k, thus preventing the system crash. (BZ#1312399) * Previously, on a system using the Infiniband mlx5 driver used for the SRP stack, a hard lockup previously occurred after the kernel exceeded time with lock held with interrupts blocked. As a consequence, the system panicked. This update fixes this bug, and the system no longer panics in this situation. (BZ#1313814) * On the little-endian variant of IBM Power Systems, the kernel previously crashed in the bitmap_weight() function while running the memory affinity script. The provided patch fortifies the topology setup and prevents sd-> child from being set to NULL when it is already NULL. As a result, the memory affinity script runs successfully. (BZ#1316158) * When a KVM guest wrote random values to the special-purpose registers (SPR) Instruction Authority Mask Register (IAMR), the guest and the corresponding QEMU process previously hung. This update adds the code which sets SPRs to a suitable neutral value on guest exit, thus fixing this bug. (BZ#1316636) * Under heavy iSCSI traffic load, the system previously panicked due to a race in the locking code leading to a list corruption. This update fixes this bug, and the system no longer panics in this situation. (BZ#1316812) * During SCSI exception handling (triggered by some irregularities), the driver could previously use an already retired SCSI command. As a consequence, a kernel panic or data corruption occurred. The provided patches fix this bug, and exception handling now proceeds successfully. (BZ #1316820) * When the previously opened /dev/tty, which pointed to a pseudo terminal (pty) pair, was the last file closed, a kernel crash could previously occur. The underlying source code has been fixed, preventing this bug. (BZ# 1320297) * Previously, when using VPLEX and FCoE via the bnx2fc driver, different degrees of data corruption occurred. The provided patch fixes the FCP Response (RSP) residual parsing in bnx2fc, which prevents the aforementioned corruption.
