A vulnerability has been identified in SIPORT MP (All versions < 3.2.1). Vulnerable versions of the device could allow an authenticated attacker to impersonate other users of the system and perform (potentially administrative) actions on behalf of those users if the single sign-on feature ("Allow logon without password") is enabled.

A vulnerability has been identified in Desigo Insight (All versions). The web service does not properly apply input validation for some query parameters in a reserved area. This could allow an authenticated attacker to retrieve data via a content-based blind SQL injection attack.

An issue was discovered in Xen through 4.14.x. x86 PV guest kernels can experience denial of service via SYSENTER. The SYSENTER instruction leaves various state sanitization activities to software. One of Xen's sanitization paths injects a #GP fault, and incorrectly delivers it twice to the guest. This causes the guest kernel to observe a kernel-privilege #GP fault (typically fatal) rather than a user-privilege #GP fault (usually converted into SIGSEGV/etc.). Malicious or buggy userspace can crash the guest kernel, resulting in a VM Denial of Service. All versions of Xen from 3.2 onwards are vulnerable. Only x86 systems are vulnerable. ARM platforms are not vulnerable. Only x86 systems that support the SYSENTER instruction in 64bit mode are vulnerable. This is believed to be Intel, Centaur, and Shanghai CPUs. AMD and Hygon CPUs are not believed to be vulnerable. Only x86 PV guests can exploit the vulnerability. x86 PVH / HVM guests cannot exploit the vulnerability.

An arbitrary code execution vulnerability exists in the rendering functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242. When drawing the contents of a page using colors from an indexed colorspace, the application can miscalculate the size of a buffer when allocating space for its colors. When using this allocated buffer, the application can write outside its bounds and cause memory corruption which can lead to code execution. A specially crafted document must be loaded by a victim in order to trigger this vulnerability.

An exploitable vulnerability exists in the cross-reference table repairing functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242. While searching for an object identifier in a malformed document that is missing from the cross-reference table, the application will save a reference to the object’s cross-reference table entry inside a stack variable. If the referenced object identifier is not found, the application may resize the cross-reference table which can change the scope of its entry. Later when the application tries to reference cross-reference entry via the stack variable, the application will access memory belonging to the recently freed table causing a use-after-free condition. A specially crafted document can be delivered by an attacker and loaded by a victim in order to trigger this vulnerability.

An exploitable vulnerability exists in the object stream parsing functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242 when updating its cross-reference table. When processing an object stream from a PDF document, the application will perform a calculation in order to allocate memory for the list of indirect objects. Due to an error when calculating this size, an integer overflow may occur which can result in an undersized buffer being allocated. Later when initializing this buffer, the application can write outside its bounds which can cause a memory corruption that can lead to code execution. A specially crafted document can be delivered to a victim in order to trigger this vulnerability.

A vulnerability has been identified in Siveillance Video Client (All versions). In environments where Windows NTLM authentication is enabled the affected client application transmits usernames to the server in cleartext. This could allow an attacker in a privileged network position to obtain valid adminstrator login names and use this information to launch further attacks.

WebDAV implementation in Yaws web server versions 1.81 to 2.0.7 is vulnerable to XXE injection.

A vulnerability has been identified in License Management Utility (LMU) (All versions < V2.4). The lmgrd service of the affected application is executed with local SYSTEM privileges on the server while its configuration can be modified by local users. The vulnerability could allow a local authenticated attacker to execute arbitrary commands on the server with local SYSTEM privileges.

A code execution vulnerability exists in the DICOM parse_dicom_meta_info functionality of Accusoft ImageGear 19.7. A specially crafted malformed file can cause an out-of-bounds write. An attacker can trigger this vulnerability by providing a victim with a malicious DICOM file.
