Integer Overflow in TeamViewer Remote Control Screen Decompression Leading to Heap-Based Buffer Overflow

An integer overflow in the remote-control screen processing component of TeamViewer clients (Full Client, Portable and Remote Control App) prior to version 15.83 may allow a malicious remote host to cause a denial of service or, depending on the platform, potentially execute arbitrary code with the privileges of the viewer process. Exploitation requires a user to establish a remote-control session to an attacker-controlled or compromised host.

Stack Buffer Overflow in Moxa Wireless Device Server Web Interface

A stack-based buffer overflow vulnerability exists in the web management interface of affected Moxa wireless device servers. An authenticated remote attacker with low privileges could exploit insufficient bounds checking of user-supplied input, causing the web management service to become unresponsive. Restoring the service requires power cycling the affected device, while other device functions remain operational.

Fireware OS NULL Pointer Dereference in Management Interface Allows Unauthenticated Denial of Service

A NULL pointer dereference vulnerability in WatchGuard Fireware OS’s management interface allows a remote, unauthenticated attacker with network access to the management interface to crash the management service by sending a specially crafted login request. Repeated exploitation terminates all active administrator sessions and in-progress management operations and can prevent management of the device. Traffic processing is not affected.

Out-of-bounds write vulnerability in QTextCodec iconv-based encoding impacts Qt

An out-of-bounds write vulnerability in the Qt QTextCodec iconv-based encoding of the Qt 5 Compatibility APIs module (Qt Core in Qt 5 and earlier) impacts Qt. Under certain conditions, encoding text with QTextCodec may write outside an internal buffer. This can cause the application to crash and may affect data integrity.

jackson-dataformat-protobuf: signed integer overflow in string-length paths allows unbounded array allocation and OutOfMemoryError

ProtobufParser parses length-prefixed protobuf string and bytes fields by checking (_inputPtr + len) <= _inputEnd and then, on the fast path, calling _finishShortText(len). Both use 32-bit signed integer arithmetic. When an attacker supplies a varint decoding to a length near Integer.MAX_VALUE, _inputPtr + len overflows to a negative value, the bounds check passes, and _finishShortText(len) reaches TextBuffer.expandCurrentSegment(len), which performs Arrays.copyOf with no cap and throws OutOfMemoryError: Requested array size exceeds VM limit. The JVM refuses arrays larger than Integer.MAX_VALUE - 8 before consulting available heap, so -Xmx tuning does not mitigate the issue. StreamReadConstraints.maxStringLength and maxDocumentLength do not gate this path: a 33-byte payload is far below any document-length cap and the string-length check does not fire before the allocation. This was confirmed empirically against shipping artifacts with maxStringLength, maxDocumentLength and maxNestingDepth all configured. A February 2026 hardening commit added the equivalent overflow guard to the packed-array-length and message-length paths but left the string-length call sites unguarded. No privileges or user interaction beyond the ability to submit data for parsing are required.

CVE-2024-31082

Xorg-x11-server: heap buffer overread/data leakage in procappledricreatepixmap

A heap-based buffer over-read vulnerability was found in the X.org server's ProcAppleDRICreatePixmap() function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a different endianness. This vulnerability could be exploited by an attacker to cause the X server to read heap memory values and then transmit them back to the client until encountering an unmapped page, resulting in a crash. Despite the attacker's inability to control the specific memory copied into the replies, the small length values typically stored in a 32-bit integer can result in significant attempted out-of-bounds reads.
