The problem seems to be related to signed/unsigned + conversion during size promotion. The function return_EIO returns an + int but its used as a ssize_t with a comparison to 0. This causes the + range check to fail and copy_to_user copies way too much. + The command line "fsfuzz iso9660" can easily reproduce this behavior. +Ubuntu-Description: + Various syscalls (like listxattr()) misinterpreted the return value + of return_EIO() when encountering bad inodes. By issuing particular + system calls on a malformed file system, a local attacker could + exploit this to crash the kernel. +Notes: +Bugs: +upstream: released (2.6.20-rc5) +linux-2.6: released (2.6.20-1) +2.6.18-etch-security: released (2.6.18.dfsg.1-13) [bugfix/listxattr-mem-corruption.patch] +2.6.8-sarge-security: released (2.6.8-16sarge7) [listxattr-mem-corruption.dpatch] +2.4.27-sarge-security: released (2.4.27-10sarge6) [261_listxattr-mem-corruption.diff] +2.6.12-breezy-security: released (2.6.12-10.43) +2.6.15-dapper-security: released (2.6.15-28.51) +2.6.17-edgy-security: released (2.6.17.1-11.35) |
