Background

libcrypto++ is a C++ cryptographic library that provides various cryptographic algorithms and functionalities. It is widely used in applications that require secure communication, encryption, and decryption. However, a bug was discovered in several ASN.1 parsing routines of libcrypto++, which could be exploited by an attacker to cause a denial of service remotely.

Vulnerability Detail

The vulnerability in libcrypto++ arises from a flaw in its ASN.1 parsing routines. This flaw allows an attacker to exploit the library and trigger a denial of service attack. By sending specially crafted ASN.1 data, an attacker can cause the library to crash or consume excessive resources, leading to a disruption of service. This vulnerability does not directly allow for remote code execution or unauthorized access to sensitive information.

How To Fix

Minimum fixed version

5.6.1-6+deb7u3

This is the first release that contains the fix.
