Resolution ========== Upgrade to 48.0-1. # pacman -Syu "firefox>=48.0-1" The problems have been fixed upstream in version 48.0. Workaround ========== None. Description =========== - CVE-2016-0718 (arbitrary code execution) Out-of-bounds read during XML parsing in Expat library. - CVE-2016-2830 (information disclosure) Favicon network connection can persist when page is closed. - CVE-2016-2835 CVE-2016-2836 (arbitrary code execution) Mozilla developers and community members reported several memory safety bugs in the browser engine used in firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code. - CVE-2016-2837 (arbitrary code execution) Buffer overflow in ClearKey Content Decryption Module (CDM) during video playback - CVE-2016-2838 (arbitrary code execution) Buffer overflow rendering SVG with bidirectional content. - CVE-2016-5250 (information disclosure) Information disclosure through Resource Timing API during page navigation. - CVE-2016-5251 (URL spoofing) Location bar spoofing via data URLs with malformed/invalid mediatypes. - CVE-2016-5252 (arbitrary code execution) Stack underflow during 2D graphics rendering. - CVE-2016-5254 (arbitrary code execution) Use-after-free when using alt key and toplevel menus. - CVE-2016-5255 (arbitrary code execution) Crash in incremental garbage collection in JavaScript. - CVE-2016-5258 (arbitrary code execution) Use-after-free in DTLS during WebRTC session shutdown. - CVE-2016-5259 (arbitrary code execution) Use-after-free in service workers with nested sync events. - CVE-2016-5260 (information disclosure) Form input type change from password to text can store plain text password in session restore file. - CVE-2016-5261 (arbitrary code execution) Integer overflow in WebSockets during data buffering. - CVE-2016-5262 (cross-site scripting) Scripts on marquee tag can execute in sandboxed iframes. - CVE-2016-5263 (type confusion) Type confusion in display transformation - CVE-2016-5264 (use after free) Use-after-free when applying SVG effects. - CVE-2016-5265 (same-origin policy bypass) Same-origin policy violation using local HTML file and saved shortcut file. - CVE-2016-5266 (information disclosure) Information disclosure and local file manipulation through drag and drop. - CVE-2016-5268 (spoofing) Spoofing attack through text injection into internal error pages. Impact ====== A remote attacker can access sensitive information, bypass policies or execute arbitrary code on the affected host.
