Debian Security Advisory DSA 417-2 [email protected]

Package : kernel-image-2.4.18-1-alpha
Vulnerability : mising boundary check
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2003-0985
Since DSA 417-1 lacked fixed kernel image files for the alpha
architecture these are added now. For completeness below is the
original advisory:
Paul Starzetz discovered a flaw in bounds checking in mremap() in
the Linux kernel (present in version 2.4.x and 2.6.x) which may
allow a local attacker to gain root privileges. Version 2.2 is not
affected by this bug.
For the stable distribution (woody) this problem has been fixed in
version 2.4.18-13 for the alpha architecture.
For the unstable distribution (sid) this problem will be fixed soon
with newly uploaded packages.
We recommend that you upgrade your kernel packages. This problem has
been fixed in the upstream version 2.4.24 as well.
