[GLSA-200409-26] Mozilla, Firefox, Thunderbird, Epiphany: New releases fix vulnerabilities |

Mozilla, Firefox, Thunderbird, Epiphany: New releases fix vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200409-26 (Mozilla, Firefox, Thunderbird, Epiphany: New releases fix vulnerabilities) Mozilla-based products are vulnerable to multiple security issues. Firstly routines handling the display of BMP images and VCards contain an integer overflow and a stack buffer overrun. Specific pages with long links, when sent using the "Send Page" function, and links with non-ASCII hostnames could both cause heap buffer overruns. Several issues were found and fixed in JavaScript rights handling: untrusted script code could read and write to the clipboard, signed scripts could build confusing grant rights dialog boxes, and when dragged onto trusted frames or windows, JavaScript links could access information and rights of the target frame or window. Finally, Mozilla-based mail clients (Mozilla and Mozilla Thunderbird) are vulnerable to a heap overflow caused by invalid POP3 mail server responses. Impact A possible hacker might be able to run arbitrary code with the rights of the user running the software by enticing the user to perform one of the following actions: view a specially-crafted BMP image or VCard, use the "Send Page" function on a malicious page, follow links with malicious hostnames, drag multiple JavaScript links in a row to another window, or connect to an untrusted POP3 mail server. A possible hacker could also use a malicious page with JavaScript to disclose clipboard contents or abuse previously-given rights to request XPI installation rights through a confusing dialog. Workaround There is no known workaround covering all vulnerabilities.
