Technical description

mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c (specifically INTEGER_oer.c). When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, the decoder fails to validate the required bytes before extracting the Most Significant Bit (MSB). This forces a precise 1-byte Heap Out-of-Bounds (OOB) Read. Because asn1c generated code is primarily deployed to parse untrusted network inputs (such as V2X network protocols, 5G telecom headers, or X.509 certificates), when the decoder processes untrusted network-originated input, a remote attacker can exploit this to cause a Denial of Service (DoS) or trigger incorrect integer interpretation in downstream applications (e.g., protocol state poisoning or logic bypass).

CVE-2026-9499—

——0An out-of-bounds read (buffer over-read) vulnerability exists in QTextCodec::codecForName() in Qt. When the function is called with a QByteArray that is not NUL-terminated (for example, one created with QByteArray::fromRawData()), the codec-name matching routine reads past the end of the supplied buffer. In most cases this results in an incorrect text codec being selected; in the worst case, if the over-read reaches unmapped memory, the process crashes (denial of service). The over-read is bounded by the length of the longest codec-name candidate, and the out-of-bounds bytes are only compared internally against Qt's fixed list of codec names, so no data is disclosed to an attacker. Applications that do not pass non-NUL-terminated QByteArrays to QTextCodec::codecForName() are not exposed. The affected code resides in the Qt5Compat module from Qt 6.0.0 onward, and in Qt Core (qtbase) in Qt 4.x and Qt 5.x.3h CVE-2026-598423.7 LOW

——0A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory.5h CVE-2026-646099.1 CRI

——0Out-of-bounds read via sun.misc.Unsafe in Apache Fory. When out-of-band zero-copy deserialization is used, readAlignedVarUint() can read beyond the bounds of the underlying buffer. Out-of-band zero-copy deserialization is an opt-in feature; applications that do not use it are not affected. This issue affects Apache Fory (formerly Apache Fury): from 0.5.0 before 1.4.0. Versions before 0.11.0 were published under the Maven coordinates org.apache.fury:fury-core. Users are recommended to upgrade to version 1.4.0, which fixes the issue.3h CVE-2026-17717.2 HIG

——13The MapSVG plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the SVGFile constructor in all versions up to, and including, 8.14.0 This is due to an incorrect conditional check that prevents file validation from taking place. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.8h CVE-2026-472558.2 HIG

——3Rsync is a file-copying tool that uses a delta-transfer algorithm to synchronize remote and local files. In versions prior to 3.4.3, the receiver-side out-of-bounds array read in rsync's recv_files() lets a malicious rsync server (or any peer acting in the sender role) deterministically crash any rsync client that pulls from it. The trigger is fully wire-protocol-level, requires no special options on the victim, and works for both rsync:// URLs and remote-shell pulls; since inc_recurse is the protocol-30+ default, any client doing a normal recursive pull against an attacker-controlled URL is exposed. A malicious server sets CF_INC_RECURSE, sends a flist whose first sorted entry is not the leading "." directory (causing parent_ndx to be set to -1), then sends a transfer record with ndx = 0 and an iflag omitting ITEM_TRANSFER, causing the receiver to read 8 bytes before the allocated pointer array and dereference the result in f_name(). The impact is crash-only: the out-of-bounds read lands in glibc mmap chunk metadata and dereferences to an unmapped low address, producing a SEGV that cannot be leveraged into an exploit (confirmed on glibc x86-64 Linux; non-glibc allocators not audited). This issue is fixed in version 3.4.3.19h
