Description Joel 2008-05-08 12:07:09 UTC

Some vulnerabilities have been reported in rdesktop, which can be exploited by malicious people to compromise a user's system.

1) An integer underflow error in iso.c when processing RDP requests can be exploited to cause a heap-based buffer overflow.

2) An input validation error in rdp.c when processing RDP redirect requests can be exploited to cause a BSS-based buffer overflow.

3) A signedness error within "xrealloc()" in rdesktop.c can be exploited to cause a heap-based buffer overflow.

Successful exploitation allows execution of arbitrary code but requires that a user is tricked into connecting to a malicious RDP server.

The vulnerabilities are reported in version 1.5.0. Other versions may also be affected.

Fixed in the CVS repository.;diff_format=h&pathrev=HEAD#l101;tr2=1.118&diff_format=h#l1134

Martin is retiring per bug #159513, so I bumped to the freshly released 1.6.0. It contains all the fixes "linked" above.
