- More information:
Multiple vulnerabilities have been found in Icedove, Debian's version of the Mozilla Thunderbird mail and news client.
The HZ-GB-2312 character-set implementation does not properly handle a ~ (tilde) character in proximity to a chunk delimiter, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.
Use-after-free vulnerability in the gfxFont::GetFontEntry function allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
Heap-based buffer overflow in the nsWindow::OnExposeEvent function could allow remote attackers to execute arbitrary code.
Multiple unspecified vulnerabilities in the browser engine could allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code.
For the stable distribution (squeeze), these problems have been fixed in version 3.0.11-1+squeeze15.
For the unstable distribution (sid), these problems have been fixed in version 10.0.11-1.
We recommend that you upgrade your icedove packages.
