CVE-2011-2182

The CVE-2011-2182 bug affects the Linux kernel’s LDM partition handling (fs/partitions/ldm.c) prior to 2.6.39.1, where memory allocation for non-initial fragments could misbehave, potentially enabling local users to trigger a buffer overflow, gain privileges, or access sensitive information when ...

CVE-2011-2182: Improper Restriction of Operations within the Bounds of a Memory Buffer

The ldmfragadd function in fs/partitions/ldm.c in the Linux kernel before 2.6.39.1 does not properly handle memory allocation for non-initial fragments, which might allow local users to conduct buffer overflow attacks, and gain privileges or obtain sensitive information, via a crafted LDM partiti...

CVE-2011-2495: Undefined Security Weakness

fs/proc/base.c in the Linux kernel before 2.6.39.4 does not properly restrict access to /proc//io files, which allows local users to obtain sensitive I/O statistics by polling a file, as demonstrated by discovering the length of another user's password...

CVE-2012-2375: Undefined Security Weakness

The nfs4getacluncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy operation, which allows remote NFS servers to cause a denial of service OOPS by sending an excessive number of bitmap words in an...

CVE-2011-2493: Undefined Security Weakness

The ext4fillsuper function in fs/ext4/super.c in the Linux kernel before 2.6.39 does not properly initialize a certain error-report data structure, which allows local users to cause a denial of service OOPS by attempting to mount a crafted ext4 filesystem...
