CVE-ID : CVE-2021-22898
Package : lib32-libcurl-gnutls
Type : information disclosure
Remote : Yes
Link : https://security.archlinux.org/AVG-2000
The package lib32-libcurl-gnutls before version 7.77.0-1 is vulnerable
to information disclosure.
Upgrade to 7.77.0-1.
The problem has been fixed upstream in version 7.77.0.
The issue can be mitigated by avoiding to use the -t command line
option and CURLOPT_TELNETOPTIONS.
A security issue has been found in curl before version 7.77.0. curl
supports the -t command line option, known as CURLOPT_TELNETOPTIONS in
libcurl. This rarely used option is used to send variable=content pairs
to TELNET servers. Due to flaw in the option parser for sending NEW_ENV
variables, libcurl could be made to pass on uninitialized data from a
stack based buffer to the server. Therefore potentially revealing
sensitive internal information to the server using a clear-text network
protocol.
curl could disclose potentially sensitive memory information to a
remote server over Telnet when an uncommon option is used.
