GLSA-201507-15 : OpenSSL: Alternate chains certificate forgery

The remote host is affected by the vulnerability described in GLSA-201507-15 OpenSSL: Alternate chains certificate forgery During certificate verification, OpenSSL attempts to find an alternative certificate chain if the first attempt to build such a chain fails. Impact : A remote attacker could...

OpenSSL 1.0.2c Alternative chains certificate forgery Vulnerability

Exploit for multiple platform in category remote exploits The function X509verifycert checks the value of |ctx-chain| at the beginning, and if it is NULL then it initialises it, along with the value of ctx-untrusted. The normal way to use X509verifycert is to first call X509STORECTXinit; then set...

openssl -- alternate chains certificate forgery vulnerability

OpenSSL reports: During certificate verification, OpenSSL starting from version 1.0.1n and 1.0.2b will attempt to find an alternative certificate chain if the first attempt to build such a chain fails. An error in the implementation of this logic can mean that an attacker could cause certain chec...

Vulnerability in OpenSSL - Alternative chains certificate forgery

An error in the implementation of the alternative certificate chain logic could allow an attacker to cause certain checks on untrusted certificates to be bypassed, such as the CA flag, enabling them to use a valid leaf certificate to act as a CA and “issue” an invalid certificate. Found by Adam...
