Denial of service
The ext4fillflexinfo function in fs/ext4/super.c in the Linux kernel before 2.6.32-git6 allows user-assisted remote attackers to cause a denial of service divide-by-zero error and panic via a malformed ext4 filesystem containing a super block with a large FLEXBG group size aka sloggroupsperflex...
Design/Logic Flaw
Unspecified vulnerability in the EXT4IOCMOVEEXT aka move extents ioctl implementation in the ext4 filesystem in the Linux kernel 2.6.32-git6 and earlier allows local users to cause a denial of service filesystem corruption via unknown vectors, a different vulnerability than CVE-2009-4131...

CVE-2009-4308
CVE-2009-4308 affects the Linux kernel ext4 filesystem: the ext4_decode_error function in fs/ext4/super.c can cause a NULL pointer dereference and potential other impact when processing a read-only, journal-less filesystem, enabling user‑assisted remote denial of service. The vulnerability is fix...
CVE-2009-4308
The ext4decodeerror function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service NULL pointer dereference, and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal...

CVE-2009-4307
The CVE-2009-4307 issue affects the Linux kernel ext4 subsystem: the ext4_fill_flex_info function in fs/ext4/super.c allows a remote attacker to trigger a divide-by-zero and panic when a malformed ext4 super block has a large FLEX_BG group size (s_log_groups_per_flex). Impact is denial of service...
CVE-2009-4131
The CVE refers to EXT4_IOC_MOVE_EXT (move extents) in the Linux kernel’s ext4 filesystem, where the ioctl allows local users to overwrite arbitrary files due to insufficient permission checks. Affected: ext4 subsystem on kernel versions prior to 2.6.32-git6. Impact: local privilege-related overwr...

Two New Flaws Haunt Linux Kernel
A pair of new kernel vulnerabilities are threatening the security of systems running current versions of several Linux distributions. One of the flaws gives a remote attacker the ability to crash vulnerable systems and the other leads to root privileges for a local attacker. The most serious of t...
