The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2015-4497 Jean-Max Reymond and Ucha Gobejishvili discovered a use-after-free vulnerability which occurs when resizing of a canvas element is triggered in concert with style changes. A web page containing malicious content can cause Iceweasel to crash, or potentially, execute arbitrary code with the privileges of the user running Iceweasel. CVE-2015-4498 Bas Venis reported a flaw in the handling of add-ons installation. A remote attacker can take advantage of this flaw to bypass the add-on installation prompt and trick a user into installing an add-on from a malicious source. For the oldstable distribution (wheezy), these problems have been fixed in version 38.2.1esr-1~deb7u1. For the stable distribution (jessie), these problems have been fixed in version 38.2.1esr-1~deb8u1. For the unstable distribution (sid), these problems have been fixed in version 38.2.1esr-1. We recommend that you upgrade your iceweasel packages.
