Description
The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
Affected configurations
• linux linux kernel (< 3.10.83)
• linux linux kernel (>= 3.11 < 3.12.45)
• linux linux kernel (>= 3.13 < 3.14.47)
• linux linux kernel (>= 3.15 < 3.16.35)
• linux linux kernel (>= 3.17 < 3.18.19)
