Synopsis ========
w3m does not correctly handle format string specifiers in SSL certificates.
Background ==========
w3m is a multi-platform text-based web browser.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/w3m < 0.5.1-r4 >= 0.5.1-r4
Description ===========
w3m in -dump or -backend mode does not correctly handle printf() format string specifiers in the Common Name (CN) field of an X.509 SSL certificate.
Impact ======
An attacker could entice a user to visit a malicious website that would load a specially crafted X.509 SSL certificate containing "%n" or other format string specifiers, possibly resulting in the execution of arbitrary code with the rights of the user running w3m.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All w3m users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/w3m-0.5.1-r4"
