EulerOS 2.0 SP9 : curl (EulerOS-SA-2021-2239)

medium Nessus Plugin ID 152334

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - curl is a command line tool for transferring data with URL syntax, supporting FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, TELNET, DICT, LDAP, LDAPS, FILE, IMAP, SMTP, POP3 and RTSP. curl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form based upload, proxies, cookies, user+password authentication (Basic, Digest, NTLM, Negotiate, kerberos...), file transfer resume, proxy tunneling and a busload of other useful tricks.Security Fix(es):A flaw was found in curl where libcurl lets applications specify which specific TLS ciphers to use in transfers, using the option called CURLOPT_SSL_CIPHER_LIST. The cipher selection is used for the TLS negotiation when a transfer is done involving any of the TLS based transfer protocols libcurl sup(CVE-2021-22897)curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a 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, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.(CVE-2021-22898)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected curl packages.
