FTP too eager connection reuse

libcurl would reuse a previously created FTP connection even when one or more options had been changed that could have made the effective user a different one, thus leading to doing the second transfer with the wrong credentials. libcurl keeps previously used connections in a connection pool for...

Internet Bug Bounty: CVE-2023-27538: SSH connection too eager reuse still

A vulnerability was found in libcurl that allowed the reuse of a previously created SSH connection even when an SSH related option had been changed that should have prohibited reuse. This was due to two SSH settings being left out from the configuration match checks, making them match too easily...

CVE-2023-27535

An authentication bypass vulnerability exists in libcurl 8.0.0 in the FTP connection reuse feature that can result in wrong credentials being used during subsequent transfers. Previously created connections are kept in a connection pool for reuse if they match the current setup. However, certain...

curl: CVE-2023-27535: FTP too eager connection reuse

A vulnerability existed in libcurl FTPS protocol that allowed the reuse of a connection even if different credentials were specified for different connections, resulting in the use of cached credentials for the wrong content. The vulnerability was caused by the failure to refuse caching when...

K52828640: libcurl vulnerability CVE-2016-8616

Security Advisory Description A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that...

curl: bad local IPv6 connection reuse

A vulnerability was found in curl. This security flaw occurs due to errors in the logic where the config matching function did not take the IPv6 address zone id into account. This issue can lead to curl reusing the wrong connection when one transfer uses a zone id, and the subsequent transfer use...

undertow: Double AJP response for 400 from EAP 7 results in CPING failures

A flaw was found in Undertow. For an AJP 400 response, EAP 7 is improperly sending two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second...
