Out-of-bounds Read
Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the INTEGERdecodeoer function. An attacker can cause a denial of service or trigger incorrect integer interpretation in downstream applications by submitting a maliciously crafted, zero-length OER payload for a...
CVE-2026-44378
A flaw was found in Botan, a C++ cryptography library. A remote attacker could exploit this vulnerability by sending specially crafted Basic Encoding Rules BER data with indefinite length encodings. This could cause quadratic behavior in the parser, leading to a denial of service DoS due to...
CVE-2026-45615
ASN.1 compiler mouse07410/asn1c (1.4 and earlier) contains a memory-safety flaw in the OER decoding skeleton (INTEGER_oer.c). Parsing a crafted, zero-length OER payload for a variable-length, non-negative INTEGER can skip required-byte validation before extracting the MSB, causing a precise 1-byt...
asn1c 安全漏洞
ASN1C is an ASN.1 compiler developed by Lev Walkin as a personal project. Versions of ASN1C prior to 1.4 contained security vulnerabilities. These vulnerabilities stemmed from memory safety issues in the OER decoding framework. When parsing specially crafted zero-length payloads, the decoder did...
Inefficient Algorithmic Complexity
Overview Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity via the BER data parsing process. An attacker can cause excessive resource consumption and service disruption by submitting specially crafted indefinite length encodings. Remediation Upgrade botan to...
CVE-2026-44378
Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...
CVE-2026-44378
Botan (C++ cryptography library) is affected prior to version 3.12.0. Indefinite-length BER encodings could trigger quadratic parser behavior, even in structures that must be DER, leading to denial of service. The issue is fixed in 3.12.0. There are no explicit exploit details or in-the-wild expl...
CVE-2026-44378 Botan: Quadratic complexity decoding BER indefinite length encodings
Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...
Botan 安全漏洞
Botan is a C++ encryption library developed by Jack Lloyd as an individual project. Versions of Botan prior to 3.12.0 contained security vulnerabilities. These vulnerabilities were caused byBER data, which led to reassembly behavior by the parser, potentially resulting in denial-of-service attack...
CVE-2026-44905
Vanetza (ETSI C-ITS) contains a denial-of-service condition in 26.02 and earlier due to a logic flaw in the cryptographic verification path. An incoming V2X certificate with a Psid subtype violation can be parsed syntactically, but semantic checks are not enforced until re-encoding during Straigh...
CVE-2026-43988
Vanetza is an open-source implementation of the ETSI C-ITS protocol suite. In 26.02 and earlier, a denial-of-service vulnerability was identified in the ASN.1/OER parsing pipeline of Vanetza. When processing malformed network packets containing corrupted ASN.1/OER structures e.g., invalid length...
Vanetza 安全漏洞
Vanetza is an open-source implementation of a vehicle communication protocol suite developed by Raphael Riebl. Versions of Vanetza prior to 26.02 contained a security vulnerability. This vulnerability occurred when processing malformed network packets in the ASN.1/OER parsing pipeline, where the...
PT-2026-42855
Name of the Vulnerable Software and Affected Versions Botan versions prior to 3.12.0 Description Certain patterns of indefinite length encodings in Basic Encoding Rules BER data can cause quadratic behavior in the parser, leading to a denial of service. These BER encodings were accepted even in...
CVE-2026-43233
In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodechoice In decodechoice, the boundary check before getlen uses the variable len, which is still 0 from its initialization at the top of the function: unsigned int type, ext, len = ...

CVE-2026-6527
A flaw was found in Wireshark, a network protocol analyzer. A local user could be affected by this vulnerability if they open a specially crafted capture file containing malformed ASN.1 PER Abstract Syntax Notation One Packed Encoding Rules protocol data. This could lead to a crash of the Wiresha...
CVE-2026-6527
ASN.1 PER protocol dissector crash in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service...
CVE-2026-6527
The CVE-2026-6527 issue affects Wireshark’s ASN.1 PER protocol dissector, with crashes observed in Wireshark versions 4.6.0–4.6.4 and 4.4.0–4.4.14 that can lead to a denial of service. The root cause is described as an uncontrolled recursion in the dissector, though explicit technical details (e....
Wireshark 安全漏洞
Wireshark is a set of network packet analysis tools developed by the Wireshark team. The software’s function is to capture network packets and display detailed data for analysis. Versions of Wireshark from 4.6.0 to 4.6.4, as well as 4.4.0 to 4.4.14, have security vulnerabilities. These...
