A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code by delivering crafted text content to a user, when this content is then rendered by an application that uses FriBidi for text layout calculations. Examples include any GNOME or GTK+ based application that uses Pango for text layout, as this internally uses FriBidi for bidirectional text layout. For example, the attacker can construct a crafted text file to be opened in GEdit, or a crafted IRC message to be viewed in HexChat.Show less

libpoe-component-irc-perl before v6.32 does not remove carriage returns and line feeds. This can be used to execute arbitrary IRC commands by passing an argument such as "some text\rQUIT" to the 'privmsg' handler, which would cause the client to disconnect from the server.Show less

If LD_LIBRARY_PATH is undefined in gargoyle-free before 2009-08-25, the variable will point to the current directory. This can allow a local user to trick another user into running gargoyle in a directory with a cracked libgarglk.so and gain access to the user's account.Show less

In tnef before 1.4.18, an attacker may be able to write to the victim's .ssh/authorized_keys file via an e-mail message with a crafted winmail.dat application/ms-tnef attachment, because of a heap-based buffer over-read involving strdup.Show less

A flaw was found in the 'deref' plugin of 389-ds-base where it could use the 'search' permission to display attribute values. In some configurations, this could allow an authenticated attacker to view private attributes, such as password hashes.Show less
