FreeBSD : libgadu -- multiple vulnerabilities (3b4a6982-0b24-11da-bc08-0001020eed82)

Critical Nessus Plugin ID 21414


The remote FreeBSD host is missing one or more security-related updates.


Wojtek Kaniewski reports :

Multiple vulnerabilities have been found in libgadu, a library for handling Gadu-Gadu instant messaging protocol. It is a part of ekg, a Gadu-Gadu client, but is widely used in other clients. Also some of the user contributed scripts were found to behave in an insecure manner.

- integer overflow in libgadu (CVE-2005-1852) that could be triggered by an incomming message and lead to application crash and/or remote code execution

- insecure file creation (CVE-2005-1850) and shell command injection (CVE-2005-1851) in other user contributed scripts (discovered by Marcin Owsiany and Wojtek Kaniewski)

- several signedness errors in libgadu that could be triggered by an incomming network data or an application passing invalid user input to the library

- memory alignment errors in libgadu that could be triggered by an incomming message and lead to bus errors on architectures like SPARC

- endianness errors in libgadu that could cause invalid behaviour of applications on big-endian architectures


Update the affected packages.
