HP One Agent Software – Security Update

Potential security vulnerabilities have been identified in the HP One Agent for certain HP PC products, which might allow for escalation of privilege and/or denial of service. HP is releasing software updates to mitigate these potential vulnerabilities.

Stack Overflow Vulnerability in AOS-10 Web-Based Management Interface

A stack overflow vulnerability exists in the AOS-10 web-based management interface of a Mobility Gateway. Successful exploitation could allow an authenticated malicious actor to execute arbitrary code as a privileged user on the underlying operating system.

Incorrect User Management

The FACSChorus software does not properly assign data access privileges for operating system user accounts. A non-administrative OS account can modify information stored in the local application data folders.

OpenSSH: Client buffer-overflow when using roaming connections

The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact by requesting many forwardings.

OpenSSH: Client Information leak due to use of roaming connection feature

The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.

libpng: use-after-free in png_image_free in png.c

png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.

hw: TSX Transaction Asynchronous Abort (TAA)

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.

An SNMP community name is the default (e.g. public), null, or missing.

LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.

HP ENVY 5000 series printers VERBASPP1N003.2237A.00 do not properly manage concurrent TCP connections to port 9100 (JetDirect/RAW printing). An unauthenticated remote attacker on the same network can establish a persistent connection to port 9100 and send keep-alive packets, causing the printer's session threads to remain locked in a waiting state. The firmware lacks connection timeouts and concurrent session limits, resulting in a persistent Denial of Service (DoS) that renders the printer unresponsive to all user commands and print jobs. Physical intervention (manual restart) is required to restore functionality, and the attack can be immediately re-initiated.

Certain HP DeskJet All In One (AIO) Devices – Potential Remote Code Execution & Potential Buffer Overflow

Certain HP DeskJet All in One devices may be vulnerable to remote code execution caused by a buffer overflow when specially crafted Web Services for Devices (WSD) scan requests are improperly validated and handled by the MFP. WSD Scan is a Microsoft Windows–based network scanning protocol that allows a PC to discover scanners (and MFPs) on a network and send scan jobs to them without requiring vendor specific drivers or utilities.

HP Linux Imaging and Printing Software – Potential Escalation of Privilege and Arbitrary Code Execution

A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This potential vulnerability may allow escalation of privileges and/or arbitrary code execution via an integer overflow in the hpcups processing path when handling crafted print data.

HP Linux Imaging and Printing Software – Potential Escalation of Privilege and Arbitrary Code Execution

A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This potential vulnerability may allow escalation of privileges and/or arbitrary code execution via operating system command injection.

Samsung Print Service Plugin – Potential Information Disclosure

Samsung Print Service Plugin for Android is potentially vulnerable to information disclosure when using an outdated version of the application via mobile devices. HP is releasing updates to mitigate these potential vulnerabilities.

Multiple heap-based buffer overflows in ovsessionmgr.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allow remote attackers to execute arbitrary code via a long (1) userid or (2) passwd parameter to ovlogin.exe.

Buffer overflow in webappmon.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via a long HTTP Host header.

Heap-based buffer overflow in OvWebHelp.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via a long Topic parameter.

Stack-based buffer overflow in ovalarm.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via a long HTTP Accept-Language header in an OVABverbose action.

Stack-based buffer overflow in snmpviewer.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to execute arbitrary code via a long HTTP Host header.
