RHEL 7 : curl (RHSA-2017:3263)

critical Nessus Plugin ID 104801

Language:

Synopsis

The remote Red Hat host is missing a security update for curl.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:3263 advisory.

The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.

Security Fix(es):

* A buffer overrun flaw was found in the IMAP handler of libcurl. By tricking an unsuspecting user into connecting to a malicious IMAP server, an attacker could exploit this flaw to potentially cause information disclosure or crash the application. (CVE-2017-1000257)

Red Hat would like to thank the Curl project for reporting this issue. Upstream acknowledges Brian Carpenter and the OSS-Fuzz project as the original reporters.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL curl package based on the guidance in RHSA-2017:3263.
