CVE-2012-3400: Buffer Overflow
First published: Wed Jul 25 2012(Updated: )
Description of problem: A specially-crafted UDF filesystem could cause buffer overflow when parsing sparing tables in udf_load_logicalvol()@fs/udf/super.c. The bug is fixed in upstream kernel via the following commits: commit 1df2ae31c724e57be9d7ac00d78db8a5dabdd050 Author: Jan Kara <jack () suse cz> Date: Wed Jun 27 21:23:07 2012 +0200 udf: Fortify loading of sparing table Add sanity checks when loading sparing table from disk to avoid accessing unallocated memory or writing to it. and commit adee11b2085bee90bd8f4f52123ffb07882d6256 Author: Jan Kara <jack () suse cz> Date: Wed Jun 27 20:20:22 2012 +0200 udf: Avoid run away loop when partition table length is corrupted Check provided length of partition table so that (possibly maliciously) corrupted partition table cannot cause accessing data beyond current buffer.
