CentOS Errata and Security Advisory CESA-2017:2016
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):
- Multiple integer overflow flaws leading to heap-based buffer overflows were found in the way curl handled escaping and unescaping of data. An attacker could potentially use these flaws to crash an application using libcurl by sending a specially crafted input to the affected libcurl functions. (CVE-2016-7167)
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.
