Red Hat Enterprise Linux 7: RHSA-2017-3263-01 Moderate: Curl Buffer Overrun

red hat
Calendar Grey November 27, 2017
Scroller Redhat
Security upgrade ready for wget with a medium severity risk on CentOS 7. Act promptly.
An update for curl is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
