Several remote vulnerabilities have been discovered in the Icedove mail client, an unbranded version of the Thunderbird mail client. The Common Vulnerabilities and Exposures project identifies the following problems:
Justin Schuh, Tom Cross and Peter Williams discovered a buffer overflow in the parser for UTF-8 URLs, which may lead to the execution of arbitrary code. (MFSA 2008-37)
It was discovered that crashes in the Javascript engine could potentially lead to the execution of arbitrary code. (MFSA 2008-20)
"moz_bug_r_a4" discovered that the same-origin check in nsXMLDocument::OnChannelRedirect() could be bypassed. (MFSA 2008-38)
"moz_bug_r_a4" discovered a vulnerability which can result in Chrome privilege escalation through XPCNativeWrappers. (MFSA 2008-41)
"moz_bug_r_a4" discovered a vulnerability which can result in Chrome privilege escalation through XPCNativeWrappers. (MFSA 2008-41)
Olli Pettay and "moz_bug_r_a4" discovered a Chrome privilege escalation vulnerability in XSLT handling. (MFSA 2008-41)
Jesse Ruderman discovered a crash in the layout engine, which might allow the execution of arbitrary code. (MFSA 2008-42)
Igor Bukanov, Philip Taylor, Georgi Guninski and Antoine Labour discovered crashes in the Javascript engine, which might allow the execution of arbitrary code. (MFSA 2008-42)
Dave Reed discovered that some Unicode byte order marks are stripped from Javascript code before execution, which can result in code being executed, which were otherwise part of a quoted string. (MFSA 2008-43)
It was discovered that a directory traversal allows attackers to read arbitrary files via a certain character. (MFSA 2008-44)
It was discovered that a directory traversal allows attackers to bypass security restrictions and obtain sensitive information. (MFSA 2008-44)
It was discovered that a buffer overflow could be triggered via a long header in a news article, which could lead to arbitrary code execution. (MFSA 2008-46)
Liu Die Yu and Boris Zbarsky discovered an information leak through local shortcut files. (MFSA 2008-47, MFSA 2008-59)
Georgi Guninski, Michal Zalewski and Chris Evan discovered that the canvas element could be used to bypass same-origin restrictions. (MFSA 2008-48)
Jesse Ruderman discovered that a programming error in the window.__proto__.__proto__ object could lead to arbitrary code execution. (MFSA 2008-50)
It was discovered that crashes in the layout engine could lead to arbitrary code execution. (MFSA 2008-52)
It was discovered that crashes in the Javascript engine could lead to arbitrary code execution. (MFSA 2008-52)
It was discovered that a crash in the nsFrameManager might lead to the execution of arbitrary code. (MFSA 2008-55)
"moz_bug_r_a4" discovered that the same-origin check in nsXMLHttpRequest::NotifyEventListeners() could be bypassed. (MFSA 2008-56)
Chris Evans discovered that quote characters were improperly escaped in the default namespace of E4X documents. (MFSA 2008-58)
Jesse Ruderman discovered that the layout engine is vulnerable to DoS attacks that might trigger memory corruption and an integer overflow. (MFSA 2008-60)
Boris Zbarsky discovered that an information disclosure attack could be performed via XBL bindings. (MFSA 2008-61)
Marius Schilder discovered that it is possible to obtain sensible data via a XMLHttpRequest. (MFSA 2008-64)
Chris Evans discovered that it is possible to obtain sensible data via a JavaScript URL. (MFSA 2008-65)
Chip Salzenberg discovered possible phishing attacks via URLs with leading whitespaces or control characters. (MFSA 2008-66)
It was discovered that it is possible to perform cross-site scripting attacks via an XBL binding to an "unloaded document." (MFSA 2008-68)
It was discovered that it is possible to run arbitrary JavaScript with chrome privileges via unknown vectors. (MFSA 2008-68)
For the stable distribution (etch) these problems have been fixed in version 1.5.0.13+1.5.0.15b.dfsg1+prepatch080614i-0etch1. Packages for s390 will be provided later.
For the upcoming stable distribution (lenny) these problems will be fixed soon.
For the unstable (sid) distribution these problems have been fixed in version 2.0.0.19-1.
We recommend that you upgrade your icedove packages.
