Debian: Security update for Chromium

Several vulnerabilities were discovered in the Chromium browser. A use-after-free vulnerability allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to display box rendering. Google Chrome allows remote attackers to obtain potentially sensitive information about client-side redirect targets via a crafted web site. Google Chrome does not properly track line boxes during rendering, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a “stale pointer.” Updated packages are available from security.debian.org.
