DEBIAN-CVE-2016-2108

The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service buffer underflow and memory corruption via an ANY field in crafted serialized data, aka the "negative zero" issue...

OpenSSL ASN.1 encoder memory corruption vulnerability

OpenSSL is a general-purpose open source cryptographic library that implements Secure Sockets Layer and Secure Transport Layer protocols and can support a variety of cryptographic algorithms, including symmetric ciphers, hashing algorithms, secure hashing algorithms, and so on. A memory corruptio...

USN-2959-1 openssl vulnerabilities

Huzaifa Sidhpurwala, Hanno Böck, and David Benjamin discovered that OpenSSL incorrectly handled memory when decoding ASN.1 structures. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2016-2108 Juraj...

Vulnerability in OpenSSL - EBCDIC overread

ASN1 Strings that are over 1024 bytes can cause an overread in applications using the X509NAMEoneline function on EBCDIC systems. This could result in arbitrary stack data being returned in the buffer...

DEBIAN-CVE-2016-2053

The asn1berdecoder function in lib/asn1decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service panic via an ASN.1 BER file that lacks a public key, leading to mishandling by the publickeyverifysignature function in crypto/asymmetrickeys/publickey.c...
