GLSA-200506-19 : SquirrelMail: Several XSS vulnerabilities
Medium Nessus Plugin ID 18545
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-19 (SquirrelMail: Several XSS vulnerabilities)
SquirrelMail is vulnerable to several cross-site scripting issues, most reported by Martijn Brinkers.
By enticing a user to read a specially crafted e-mail or using a manipulated URL, an attacker can execute arbitrary scripts running in the context of the victim's browser. This could lead to a compromise of the user's webmail account, cookie theft, etc.
There is no known workaround at this time.
SolutionAll SquirrelMail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=mail-client/squirrelmail-1.4.4' Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
