Security update for curl

This update for curl fixes the following issues:

  • CVE-2022-27781: Fixed an issue where curl will get stuck in an infinite loop when trying to retrieve details about a TLS server's certificate chain (bnc#1199223).
  • CVE-2022-27782: Fixed an issue where TLS and SSH connections would be reused even when a related option had been changed (bsc#1199224).
  • CVE-2022-32206: Fixed an uncontrolled memory consumption issue caused by an unbounded number of compression layers (bsc#1200735).
  • CVE-2022-32208: Fixed an incorrect message verification issue when performing FTP transfers using krb5 (bsc#1200737).

Описание

libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.

Описание

libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.

Описание

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.

Описание

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.
