MiracleLinux 7 : curl-7.29.0-42.el7.1 (AXSA:2017-2424:02)

critical Nessus Plugin ID 289854

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2017-2424:02 advisory.

* 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) Asianux would like to thank the Curl project for reporting this issue. Upstream acknowledges Brian Carpenter and the OSS-Fuzz project as the original reporters.
CVE-2017-1000257 An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function. libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.

Tenable has extracted the preceding description block directly from the MiracleLinux 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 affected curl, libcurl and / or libcurl-devel packages.
