Concurrency vulnerability in Mozilla Firefox 1.5.0.6 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via multiple Javascript timed events that load a deeply nested XML file, followed by redirecting the browser to another page, which leads to a concurrency failure that causes structures to be freed incorrectly, as demonstrated by (1) ffoxdie and (2) ffoxdie3. NOTE: it has been reported that Netscape 8.1 and K-Meleon 1.0.1 are also affected by ffoxdie. Mozilla confirmed to CVE that ffoxdie and ffoxdie3 trigger the same underlying vulnerability. NOTE: it was later reported that Firefox 2.0 RC2 and 1.5.0.7 are also affected.Show less

Cross-domain vulnerability in Mozilla Firefox allows remote attackers to access restricted information from other domains via an object tag with a data parameter that references a link on the attacker's originating site that specifies a Location HTTP header that references the target site, which then makes that content available through the outerHTML attribute of the object. NOTE: this description was based on a report that has since been retracted by the original authors. The authors misinterpreted their test results. Other third parties also disputed the original report. Therefore, this is not a vulnerability. It is being assigned a candidate number to provide a clear indication of its statusShow less

HTTP response smuggling vulnerability in Mozilla Firefox and Thunderbird before 1.5.0.4, when used with certain proxy servers, allows remote attackers to cause Firefox to interpret certain responses as if they were responses from two different sites via (1) invalid HTTP response headers with spaces between the header name and the colon, which might not be ignored in some cases, or (2) HTTP 1.1 headers through an HTTP 1.0 proxy, which are ignored by the proxy but processed by the client.Show less
