Arch Linux Security Advisory ASA-201710-34 ========================================== Severity: Critical Date : 2017-10-29 CVE-ID : CVE-2017-13089 CVE-2017-13090 CVE-2017-6508 Package : wget Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-473 Summary ======= The package wget before version 1.19.2-1 is vulnerable to multiple issues including arbitrary code execution and content spoofing. Resolution ========== Upgrade to 1.19.2-1. # pacman -Syu "wget>=1.19.2-1" The problems have been fixed upstream in version 1.19.2. Workaround ========== None. Description =========== - CVE-2017-13089 (arbitrary code execution) A stack-based buffer overflow has been found in the HTTP protocol handling code of wget < 1.19.2, when processing chunked, encoded HTTP responses. By tricking an unsuspecting user into connecting to a malicious HTTP server, an attacker could exploit this flaw to potentially execute arbitrary code. - CVE-2017-13090 (arbitrary code execution) A heap-based buffer overflow has been found in the HTTP protocol handling code of wget < 1.19.2, when processing chunked encoded HTTP responses. By tricking an unsuspecting user into connecting to a malicious HTTP server, an attacker could exploit this flaw to potentially execute arbitrary code. - CVE-2017-6508 (content spoofing) A CRLF injection flaw was found in the way wget < 1.19.2 handled URLs. A remote attacker could use this flaw to inject arbitrary HTTP headers in requests, via CRLF sequences in the host sub-component of a URL, by tricking a user running wget into processing crafted URLs. Impact ====== By tricking an unsuspecting user into connecting to a malicious host a remote attacker is able to execute arbitrary code or spoof returned data.
