CVE-2010-4158

[Stefan Bader]

The sk_run_filter function in net/core/filter.c in the Linux kernel before 2.6.36.2 does not check whether a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM instruction, which allows local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter.

[Stefan Bader (smb)]

Upstream fix included in 2.6.37-rc2

[Stefan Bader (smb)]

Released in Ubuntu-2.6.35-25.43 (2.6.35.10 upstream stable)

[Martin Pitt (pitti)]

Accepted linux-ec2 into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
