Description: A vulnerability has been reported in IRIX, which can be exploited by malicious, local users to cause a DoS (Denial of Service) on a vulnerable system. The problem is that any user-space program is allowed to set a watch point using the "PIOCSWATCH" command via an "ioctl()" call. This can be exploited to cause a kernel panic by constructing a malicious program. Solution: The vulnerability will be fixed in IRIX 6.5.21. SGI has furthermore issued patches for versions 6.5.17 to 6.5.20: IRIX 6.5.17m: ftp://patches.sgi.com/support/free/security/patches/6.5.17/patch5087.tar IRIX 6.5.17f: ftp://patches.sgi.com/support/free/security/patches/6.5.17/patch5088.tar IRIX 6.5.18m: ftp://patches.sgi.com/support/free/security/patches/6.5.18/patch5097.tar IRIX 6.5.18f: ftp://patches.sgi.com/support/free/security/patches/6.5.18/patch5098.tar IRIX 6.5.19m: ftp://patches.sgi.com/support/free/se...h5101.tar (All platforms except IP35) ftp://patches.sgi.com/support/free/se...6.5.19/patch5058.tar (IP35 platforms) IRIX 6.5.19f: ftp://patches.sgi.com/support/free/se...h5102.tar (All platforms except IP35) ftp://patches.sgi.com/support/free/se...6.5.19/patch5064.tar (IP35 platforms) IRIX 6.5.20m: ftp://patches.sgi.com/support/free/se...h5079.tar (All platforms except IP35) ftp://patches.sgi.com/support/free/se...6.5.20/patch5099.tar (IP35 platforms) IRIX 6.5.20f: ftp://patches.sgi.com/support/free/se...h5080.tar (All platforms except IP35) ftp://patches.sgi.com/support/free/se...6.5.20/patch5100.tar (IP35 platforms) Original Advisory: ftp://patches.sgi.com/support/free/security/advisories/20030603-01-P
