Description

The ROSE protocol implementation in the Linux kernel before 2.6.39 does not verify that certain data-length values are consistent with the amount of data sent, which might allow remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) via crafted data to a ROSE socket.

Affected products

Linux kernel: through 2.6.38.8; 2.6.38, 2.6.38-rc1, 2.6.38-rc2, 2.6.38-rc3, 2.6.38-rc4, 2.6.38-rc5 (+10)
Novell Suse Linux Enterprise Server: 10.0-sp4
