AOL versions up to and including 9.5 includes an ActiveX control (Phobos.dll) that exposes a method called Import() via the Phobos.Playlist COM object. This method is vulnerable to a stack-based buffer overflow when provided with an excessively long string argument. Exploitation allows remote attackers to execute arbitrary code in the context of the user, but only when the malicious HTML file is opened locally, due to the control not being marked safe for scripting or initialization. AOL remains an active and supported brand offering services like AOL Mail and AOL Desktop Gold, but the legacy AOL 9.5 desktop software—specifically the version containing the vulnerable Phobos.dll ActiveX control—is long discontinued and no longer maintained.

AOL Desktop 9.6 contains a buffer overflow vulnerability in its Tool\rich.rct component when parsing .rtx files. By embedding an overly long string in a hyperlink tag, an attacker can trigger a stack-based buffer overflow due to the use of unsafe strcpy operations. This allows remote attackers to execute arbitrary code when a victim opens a malicious .rtx file. AOL Desktop is end-of-life and no longer supported. Users are encouraged to migrate to AOL Desktop Gold or alternative platforms.

UNSUPPORTED WHEN ASSIGNED A vulnerability was found in AOL AIM Triton 1.0.4. It has been declared as problematic. This vulnerability affects unknown code of the component Invite Handler. The manipulation of the argument CSeq leads to denial of service. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-256318 is the identifier assigned to this vulnerability. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

The DailyFinance - Stocks & News (aka com.aol.mobile.dailyFinance) application 2.0.2.1 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

AOL Instant Messenger (AIM) 1.0.1.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Directory traversal vulnerability in iChat in Apple Mac OS X 10.5.8, and 10.6 before 10.6.4, when AIM is used, allows remote attackers to create arbitrary files via directory traversal sequences in an inline image-transfer operation.

AOLserver 4.5.1 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.

Use-after-free vulnerability in the Sb.SuperBuddy.1 ActiveX control (sb.dll) in America Online (AOL) 9.5.0.1 allows remote attackers to trigger memory corruption or possibly execute arbitrary code via a malformed argument to the SetSuperBuddy method.

A heap overflow flaw was found in a regular expression parser in the NSS library used to match common names in certificates. A malicious site could present a carefully crafted certificate in such a way as to trigger the heap overflow leading to a crash or possibly execute arbitrary code as the user running a browser such as firefox.

The overflow happens when the browser checks if the hostname of the site you are visiting matches the Common Name (CN) field of the presented certificate. This check (certTestHostName) only happens automatically if the certificate is one that is signed by a Certificate Authority you have previously trusted. If the attacker presents a malicious self-signed certificate, or one signed by an untrusted CA, the user is presented with a dialog box about the certificate before the vulnerable function is called. If the user chooses to accept the certificate then the vulnerable function is called and the heap overflow happens. So this issue does require slightly more user interaction to be exploited.

Co-incidentally, the handling of regular expressions for NSS versions 3.12.3 and above was changed to use a different and simpler regular expression routine which is not vulnerable to this issue. Therefore where a system has NSS 3.12.3 installed, it is not vulnerable to this issue by default. (Although it is possible to change Firefox back to use the old vulnerable library it is not something that is expected users to have done, and is not an obvious documented ability)

For Red Hat Enterprise Linux 5, Firefox uses the system provided NSS library. This library was updated to a versions greater than 3.12.3 by RHBA-2009:1161 on 20th July 2009. Therefore systems updated to RHBA-2009:1161 are protected by default from this issue.

For Red Hat Enterprise Linux 4, Firefox uses the system provided NSS library. This library is due to be updated to a version greater than 3.12.3 and this will probably happen within the week (so before the embargo lifts).

For Red Hat Enterprise Linux 3 we do not ship Firefox but instead SeaMonkey which provides the NSS library. SeaMonkey will need updating to correct this issue.

Multiple buffer overflows in the AIM PicEditor 9.5.1.8 ActiveX control in YGPPicEdit.dll in AOL You've Got Pictures (YGP) Picture Editor allow remote attackers to cause a denial of service (browser crash) via a long string in the (1) DisplayName, (2) FinalSavePath, (3) ForceSaveTo, (4) HiddenControls, (5) InitialEditorScreen, (6) Locale, (7) Proxy, and (8) UserAgent property values.

The embedded Internet Explorer server control in AOL Instant Messenger (AIM) 6.5.3.12 and earlier allows remote attackers to execute arbitrary code via unspecified web script or HTML in an instant message, related to AIM's filtering of "specific tags and attributes" and the lack of Local Machine Zone lockdown. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2007-4901.

The embedded Internet Explorer server control in AOL Instant Messenger (AIM) 6.1.41.2 and 6.2.32.1, AIM Pro, and AIM Lite does not properly constrain the use of mshtml.dll's web script and HTML functionality for incoming instant messages, which allows remote attackers to place HTML into unexpected contexts or execute arbitrary code, as demonstrated by writing arbitrary HTML to a notification window, and writing contents of arbitrary local image files to this window via IMG SRC.
