  script_tag(name:"insight", value:"An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers.(CVE-2022-27774)

A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number.(CVE-2022-27776)

curl < 7.84.0 supports 'chained' HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable 'links' in this 'decompression chain' was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a 'malloc bomb', makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.(CVE-2022-32206)

When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly. This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject data to the client.(CVE-2022-32208)

When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a'sister site' to deny service to all siblings.(CVE-2022-35252)

A vulnerability was found in curl. In this issue, curl can be asked to tunnel all protocols virtually it supports through an HTTP proxy. HTTP proxies can deny these tunnel operations using an appropriate HTTP error response code. When getting denied to tunnel the specific SMB or TELNET protocols, curl can use a heap-allocated struct after it has been freed and shut down the code path in its transfer.(CVE-2022-43552)

When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST.(CVE-2022-32221)

An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the 'chained' HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable 'links' in this 'decompression chain' wascapped, but the cap was ... [Please see the references for more information on the vulnerabilities]");
