LinPopUp contains a buffer overflow potentially allowing execution of
LinPopUp is a graphical application that acts as a frontend to
Samba client messaging functions, allowing a Linux desktop to
communicate with a Microsoft Windows computer that runs Winpopup.
Stephen Dranger discovered that LinPopUp contains a buffer
overflow in string.c, triggered when replying to a remote user message.
A remote attacker could craft a malicious message that, when
replied using LinPopUp, would exploit the buffer overflow. This would
result in the execution of arbitrary code with the privileges of the
user running LinPopUp.
There is no known workaround at this time.
All LinPopUp users should upgrade to the latest version:
