EulerOS 2.0 SP3 : curl (EulerOS-SA-2021-2577)

low Nessus Plugin ID 154399

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - 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.
