Synopsis ========
Insecure usage of server provided filenames may allow the creation or overwriting of local files.
Background ==========
GNU Wget is a free software package for retrieving files using HTTP, HTTPS and FTP, the most widely-used Internet protocols.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/wget < 1.12-r2 >= 1.12-r2
Description ===========
It was discovered that Wget was unsafely trusting server-provided filenames. This allowed attackers to overwrite or create files on the user's system by sending a redirect from the expected URL to another URL specifying the targeted file.
Impact ======
An unauthenticated remote attacker may be able to create or overwrite local files by enticing the user to open an attacker controlled URL, possibly leading to execution of arbitrary code.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Wget users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/wget-1.12-r2"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 19, 2010. It is likely that your system is already no longer affected by this issue.
