In practice most of the security exposure was from -the openfs path, since this meant if there was a carefully crafted -file system, buffer overrun would be triggered when the file system was -opened. - -However, if corrupted file system didn't trip over some corruption -check, and then the file system was modified via tune2fs or debugfs, -such that the superblock was marked dirty and then written out via the -closefs() path, it's possible that the buffer overrun could be -triggered when the file system is closed. - -Also clear up a signed vs unsigned warning while we're at it. - -Thanks to Nick Kralevich <nnk@google.com> for asking me to look at -compiler warning in the code in question, which led me to notice the -bug in f66e6ce4446. - -Addresses: CVE-2015-1572 - -Signed-off-by: Theodore Ts'o <tytso@mit.edu> ---- - lib/ext2fs/closefs.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - -diff --git a/lib/ext2fs/closefs.c b/lib/ext2fs/closefs.c -index 1f99113..ab5b2fb 100644 ---- a/lib/ext2fs/closefs.c -+++ b/lib/ext2fs/closefs.c -@@ -287,7 +287,7 @@ errcode_t ext2fs_flush2(ext2_filsys fs, int flags) - dgrp_t j; - #endif - char *group_ptr; -- int old_desc_blocks; -+ blk64_t old_desc_blocks; - struct ext2fs_numeric_progress_struct progress; - - EXT2_CHECK_MAGIC(fs, EXT2_ET_MAGIC_EXT2FS_FILSYS); -@@ -346,7 +346,7 @@ errcode_t ext2fs_flush2(ext2_filsys fs, int flags) - group_ptr = (char *) group_shadow; - if (fs->super->s_feature_incompat & EXT2_FEATURE_INCOMPAT_META_BG) { - old_desc_blocks = fs->super->s_first_meta_bg; -- if (old_desc_blocks > fs->super->s_first_meta_bg) -+ if (old_desc_blocks > fs->desc_blocks) - old_desc_blocks = fs->desc_blocks; - } else - old_desc_blocks = fs->desc_blocks; --- -2.1.0 - |
