Description: Scott Sinclair has reported a vulnerability in irssi, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an error in the "dcc_ctcp_resume_parse()" function in "dcc-resume.c". This can be exploited to crash a vulnerable client by sending a specially crafted DCC ACCEPT message with too few parameters. Solution: Apply updated packages. -- Ubuntu 5.10 (Breezy Badger) -- Source archives: http://security.ubuntu.com/ubuntu/poo...xt_0.8.9+0.8.10rc5-0ubuntu4.1.diff.gz Size/MD5: 12568 50ec4fee5eaf55ba7a312373bbaca462 http://security.ubuntu.com/ubuntu/poo...i-text_0.8.9+0.8.10rc5-0ubuntu4.1.dsc Size/MD5: 739 23ccac99b2a8f82d47cb1cc5f9a51ac8 http://security.ubuntu.com/ubuntu/poo...rssi-text_0.8.9+0.8.10rc5.orig.tar.gz Size/MD5: 1192158 7c0b6c1533c85e918f41ded1238e4ca1 amd64 architecture (Athlon64, Opteron, EM64T Xeon) http://security.ubuntu.com/ubuntu/poo..._0.8.9+0.8.10rc5-0ubuntu4.1_amd64.deb Size/MD5: 955832 134ebeda2593d742a808a79b78a9f488 i386 architecture (x86 compatible Intel/AMD) http://security.ubuntu.com/ubuntu/poo...t_0.8.9+0.8.10rc5-0ubuntu4.1_i386.deb Size/MD5: 851690 854b0e9e9ff3a73160a71d1b5445d850 powerpc architecture (Apple Macintosh G3/G4/G5) http://security.ubuntu.com/ubuntu/poo....8.9+0.8.10rc5-0ubuntu4.1_powerpc.deb Size/MD5: 937644 73f7b5547d9905e95006889dbc92082b Provided and/or discovered by: Reported by Scott Sinclair.
