Siemens Industrial Devices using libcurl Use After Free (CVE-2021-22924)

libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths case insensitively,which could lead ...

Moderate: curl security update

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

The libcurl library vulnerability is related to FTP connection reuse, previously created connections are stored in a connection pool for reuse if they match the current connection pool. connections are stored in the connection pool for reuse if they match the current configuration. configuration...

A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks two threads sharing the same HSTS data could end up doing a double-free or use-after-free.

curl: CVE-2023-28320: siglongjmp race condition

A race condition vulnerability existed in libcurl's siglongjmp call when using the USEALARMTIMEOUT codepath for DNS resolution. If two threads performed DNS resolving, a wrong register context could be used on the signal handler siglongjmp call if DNS timeout occurred, resulting in a segmentation...

An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However two SSH settings were omitted from the configuration check allowing them to match easily potentially leading to the reuse of an inappropriate connection.

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 FTP settings such as CURLOPT_FTP_ACCOUNT CURLOPT_FTP_ALTERNATIVE_TO_USER CURLOPT_FTP_SSL_CCC and CURLOPT_USE_SSL were not included in the configuration match checks causing them to match too easily. This could lead to libcurl using the wrong credentials when performing a transfer potentially allowing unauthorized access to sensitive information.

...

An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can reuse previously established connections with incorrect user permissions due to a failure to check for changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI transfers and could potentially result in unauthorized access to sensitive information. The safest option is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.
