Red Hat 7 RHSA-2017:3075-01 Important: Wget Buffer Overflow

red hat
Calendar Grey October 26, 2017
Scroller Redhat
Crucial wget security enhancement for Red Hat Enterprise Linux tackles severe buffer overflow vulnerabilities. More information available.
An update for wget 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 wget packages provide the GNU Wget file retrieval utility for HTTP, HTTPS, and FTP protocols.
Security Fix(es):
* A stack-based and a heap-based buffer overflow flaws were found in wget when processing chunked encoded HTTP responses. By tricking an unsuspecting user into connecting to a malicious HTTP server, an attacker could exploit these flaws to potentially execute arbitrary code. (CVE-2017-13089, CVE-2017-13090)
Red Hat would like to thank the GNU Wget project for reporting these issues.
