libtasn1: stack overflow in asn1_der_decoding

A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library...

Updated openvpn packages fix security vulnerabilities

It was possible to trigger an assertion by sending a malformed IPv6 packet. That issue could have been abused to remotely shutdown an openvpn server or client, if IPv6 and --mssfix were enabled and if the IPv6 networks used inside the VPN were known CVE-2017-7508. Some parts of the...

Bump to 1.8.3 - Security fix for CVE-2017-8932 - add support for 28+bit OIDs in asn1 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website. Tenable has attempted to automatically clean and format it as much as possible...

ALPINE-CVE-2017-10790

The asn1checkidentifier function in GNU Libtasn1 through 4.12 causes a NULL pointer dereference and crash when reading crafted input that triggers assignment of a NULL value within an asn1node structure. It may lead to a remote denial of service attack...

openSUSE Security Update : openvpn (openSUSE-2017-730)

This update for openvpn fixes the following issues : - Some parts of the certificate-parsing code did not always clear all allocated memory. This would have allowed clients to leak a few bytes of memory for each connection attempt, thereby facilitating a quite inefficient DoS attack on the server...

Copy-Paste Vulnerability (CVE) Denial Of Service (DoS)

CryptoppECC contains a copy of the Crypto++ aka cryptopp and libcrypto++ library inside it. The version that it contains is vulnerable to a denial of service DoS attack through the mishandling of the ASN1 encoding. Crypto++ allocates a SecByteBlock of the size that the ASN1 decoder reads as the...

GnuTLS libtasn1 "asn1_find_node()" buffer overflow vulnerability

Libtasn1 is the ASN.1 library used by GnuTLS. A buffer overflow vulnerability exists in the "asn1findnode" function in lib/parseraux.c in the GnuTLS libtasn1, which could allow an attacker to stack buffer overflows by tricking the user into processing specially designed job files through utilitie...

CVE-2017-9347
