Stack-based buffer overflow in the SetClientInfo function in the CDDBControlAOL.CDDBAOLControl ActiveX control (cddbcontrol.dll), as used in America Online (AOL) 7.0 4114.563, 8.0 4129.230, and 9.0 Security Edition 4156.910, and possibly other products, allows remote attackers to execute arbitrary code via a long ClientId argument.

The LinkSBIcons method in the SuperBuddy ActiveX control (Sb.SuperBuddy.1) in America Online 9.0 Security Edition dereferences an arbitrary function pointer, which allows remote attackers to execute arbitrary code via a modified pointer value.

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.

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.

Stack-based buffer overflow in AOL AOLMediaPlaybackControl (AOLMediaPlaybackControl.exe), as used by AmpX ActiveX control (AmpX.dll), might allow remote attackers to execute arbitrary code via the AppendFileToPlayList method.

Multiple stack-based buffer overflows in the AOL AmpX ActiveX control in AmpX.dll 2.6.1.11 in AOL Radio allow remote attackers to execute arbitrary code via long arguments to unspecified methods.

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.

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.
