The original update lacked recompiled ALSA modules against the new  kernel ABI. Furthermore, kernel-latest-2.4-sparc now correctly  depends on the updated packages. For completeness we're providing the  original problem description :

  Several local and remote vulnerabilities have been discovered in the   Linux kernel that may lead to a denial of service or the execution   of arbitrary code. The Common Vulnerabilities and Exposures project   identifies the following problems :

    - CVE-2004-0887       Martin Schwidefsky discovered that the privileged       instruction SACF (Set Address Space Control Fast) on       the S/390 platform is not handled properly, allowing       for a local user to gain root privileges.

    - CVE-2004-1058       A race condition allows for a local user to read the       environment variables of another process that is still       spawning through /proc/.../cmdline.

    - CVE-2004-2607       A numeric casting discrepancy in sdla_xfer allows       local users to read portions of kernel memory via a       large len argument which is received as an int but       cast to a short, preventing read loop from filling a       buffer.

    - CVE-2005-0449       An error in the skb_checksum_help() function from the       netfilter framework has been discovered that allows       the bypass of packet filter rules or a denial of       service attack.

    - CVE-2005-1761       A vulnerability in the ptrace subsystem of the IA-64       architecture can allow local attackers to overwrite       kernel memory and crash the kernel.

    - CVE-2005-2457       Tim Yamin discovered that insufficient input       validation in the compressed ISO file system (zisofs)       allows a denial of service attack through maliciously       crafted ISO images.

    - CVE-2005-2555       Herbert Xu discovered that the setsockopt() function       was not restricted to users/processes with the       CAP_NET_ADMIN capability. This allows attackers to       manipulate IPSEC policies or initiate a denial of       service attack.

    - CVE-2005-2709       Al Viro discovered a race condition in the /proc       handling of network devices. A (local) attacker could       exploit the stale reference after interface shutdown       to cause a denial of service or possibly execute code       in kernel mode.

    - CVE-2005-2973       Tetsuo Handa discovered that the udp_v6_get_port()       function from the IPv6 code can be forced into an       endless loop, which allows a denial of service attack.

    - CVE-2005-3257       Rudolf Polzer discovered that the kernel improperly       restricts access to the KDSKBSENT ioctl, which can       possibly lead to privilege escalation.

    - CVE-2005-3783       The ptrace code using CLONE_THREAD didn't use the       thread group ID to determine whether the caller is       attaching to itself, which allows a denial of service       attack.

    - CVE-2005-3806       Yen Zheng discovered that the IPv6 flow label code       modified an incorrect variable, which could lead to       memory corruption and denial of service.

    - CVE-2005-3848       Ollie Wild discovered a memory leak in the       icmp_push_reply() function, which allows denial of       service through memory consumption.

    - CVE-2005-3857       Chris Wright discovered that excessive allocation of       broken file lock leases in the VFS layer can exhaust       memory and fill up the system logging, which allows       denial of service.

    - CVE-2005-3858       Patrick McHardy discovered a memory leak in the       ip6_input_finish() function from the IPv6 code, which       allows denial of service.

    - CVE-2005-4618       Yi Ying discovered that sysctl does not properly       enforce the size of a buffer, which allows a denial of       service attack.

  - CVE-2005-1767     A vulnerability has been discovered in the stack segment     fault handler that could allow a local attacker to cause     a stack exception that will lead the kernel to crash     under certain circumstances.

  - CVE-2005-2456     Balazs Scheidler discovered that a local attacker could     call setsockopt() with an invalid xfrm_user policy     message which would cause the kernel to write beyond the     boundaries of an array and crash.

  - CVE-2005-2458     Vladimir Volovich discovered a bug in the zlib routines     which are also present in the Linux kernel and allows     remote attackers to crash the kernel.

  - CVE-2005-2459     Another vulnerability has been discovered in the zlib     routines which are also present in the Linux kernel and     allows remote attackers to crash the kernel.

  - CVE-2005-2548     Peter Sandstrom noticed that snmpwalk from a remote host     could cause a denial of service (kernel oops from null     dereference) via certain UDP packets that lead to a     function call with the wrong argument.

  - CVE-2005-2801     Andreas Gruenbacher discovered a bug in the ext2 and     ext3 file systems. When data areas are to be shared     among two inodes not all information were compared for     equality, which could expose wrong ACLs for files.

  - CVE-2005-2872     Chad Walstrom discovered that the ipt_recent kernel     module on 64-bit processors such as AMD64 allows remote     attackers to cause a denial of service (kernel panic)     via certain attacks such as SSH brute force.

  - CVE-2005-3105     The mprotect code on Itanium IA-64 Montecito processors     does not properly maintain cache coherency as required     by the architecture, which allows local users to cause a     denial of service and possibly corrupt data by modifying     PTE protections.

  - CVE-2005-3106     A race condition in the thread management may allow     local users to cause a denial of service (deadlock) when     threads are sharing memory and waiting for a thread that     has just performed an exec.

  - CVE-2005-3107     When one thread is tracing another thread that shares     the same memory map a local user could cause a denial of     service (deadlock) by forcing a core dump when the     traced thread is in the TASK_TRACED state.

  - CVE-2005-3108     A bug in the ioremap() system call has been discovered     on the amd64 architecture that could allow local users     to cause a denial of service or an information leak when     performing a lookup of a non-existent memory page.

  - CVE-2005-3109     The HFS and HFS+ (hfsplus) modules allow local attackers     to cause a denial of service (oops) by using hfsplus to     mount a filesystem that is not hfsplus.

  - CVE-2005-3110     A race condition in the ebtables netfilter module on an     SMP system running under high load may allow remote     attackers to cause a denial of service (crash).

  - CVE-2005-3271     Roland McGrath discovered that exec() does not properly     clear posix-timers in multi-threaded environments, which     results in a resource leak and could allow a large     number of multiple local users to cause a denial of     service by using more posix-timers than specified by the     quota for a single user.

  - CVE-2005-3272     The kernel allows remote attackers to poison the bridge     forwarding table using frames that have already been     dropped by filtering, which can cause the bridge to     forward spoofed packets.

  - CVE-2005-3273     The ioctl for the packet radio ROSE protocol does not     properly verify the arguments when setting a new router,     which allows attackers to trigger out-of-bounds errors.

  - CVE-2005-3274     A race condition on SMP systems allows local users to     cause a denial of service (null dereference) by causing     a connection timer to expire while the connection table     is being flushed before the appropriate lock is     acquired.

  - CVE-2005-3275     An error in the NAT code allows remote attackers to     cause a denial of service (memory corruption) by causing     two packets for the same protocol to be NATed at the     same time, which leads to memory corruption.

  - CVE-2005-3276     A missing memory cleanup in the thread handling routines     before copying data into userspace allows a user process     to obtain sensitive information.

This update also contains a number of corrections for issues that turned out to have no security implication afterwards.
