+
CVE-2023-27533
+
+ curl supports communicating using the TELNET protocol + and as a part of this it offers users to pass on user + name and "telnet options" for the server + negotiation. + + Due to lack of proper input scrubbing and without it + being the documented functionality, curl would pass on + user name and telnet options to the server as + provided. This could allow users to pass in carefully + crafted content that pass on content or do option + negotiation without the application intending to do + so. In particular if an application for example allows + users to provide the data or parts of the data. +
+
CVE-2023-27534
+
+ curl supports SFTP transfers. curl's SFTP implementation + offers a special feature in the path component of URLs: + a tilde (~) character as the first path element in the + path to denotes a path relative to the user's home + directory. This is supported because of wording in the + once proposed to-become RFC draft that was to dictate + how SFTP URLs work. + + Due to a bug, the handling of the tilde in SFTP path did + however not only replace it when it is used stand-alone + as the first path element but also wrongly when used as + a mere prefix in the first element. + + Using a path like /~2/foo when accessing a server using + the user dan (with home directory /home/dan) would then + quite surprisingly access the file /home/dan2/foo. + + This can be taken advantage of to circumvent filtering + or worse. +
+
CVE-2023-27535
+
+ 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 very different one, + thus leading to the doing the second transfer with wrong + credentials. + + libcurl keeps previously used connections in a + connection pool for subsequent transfers to reuse if one + of them matches the setup. However, several FTP settings + were left out from the configuration match checks, + making them match too easily. The settings in questions + are CURLOPT_FTP_ACCOUNT, + CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC and + CURLOPT_USE_SSL level. +
+
CVE-2023-27536
+
+ ibcurl would reuse a previously created connection even + when the GSS delegation (CURLOPT_GSSAPI_DELEGATION) + option had been changed that could have changed the + user's permissions in a second transfer. + + libcurl keeps previously used connections in a + connection pool for subsequent transfers to reuse if one + of them matches the setup. However, this GSS delegation + setting was left out from the configuration match + checks, making them match too easily, affecting + krb5/kerberos/negotiate/GSSAPI transfers. +
+
CVE-2023-27537
+
+ libcurl supports 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. +
+
CVE-2023-27538
+
+ libcurl would reuse a previously created connection even + when an SSH related option had been changed that should + have prohibited reuse. + + libcurl keeps previously used connections in a + connection pool for subsequent transfers to reuse if one + of them matches the setup. However, two SSH settings + were left out from the configuration match checks, + making them match too easily. +
