solutions Security update for Linux kernel SuSE Linux Maintenance Web (7af6f6d1031c21dd31baae6a116e2261)
Product(s): SuSE Linux Enterprise Server 8 for IBM zSeries
- CAN-2004-1068: Missing serialization in unix_dgram_recvmsg() could lead to elevated privileges, making it possible for a local attacker to gain root access. Thanks to Paul Starzetz for pointing out this problem.
- CAN-2004-1016: Missing integer overflow checks in sendmsg / control message handling allows a local attacker to crash or halt the machine. This was independent found by Paul Starzetz and Georgi Guninski, and fixed by Herbert Xu.
- A memory leak in the IP option handling in the sendmsg() system call that was reported by Georgi Guninski.
- CAN-2004-1137: Some of the pointer handling in the Linux IGMP code was broken and could allow a local attacker to crash the machine. This was found by Paul Starzetz and fixed by Chris Wright.
- A race condition in SCSI I/O accounting which could lead to erroneous reports on SCSI disk I/O was fixed.
- A memory leak in addition / removal of SCSI target devices was fixed.
- The "memfrac" and "lower_zone_reserve" kernel parameters had no effect since they were used before kernel commandline parsing.
- IBM Code drop 2004-12-03
- lcs: Replace the original lcs driver with the backport of the lcs driver for Linux kernel 2.6.
- Problem-ID: 12638 dasd: I/O errors in combination with busy condition.
- Problem-ID: 12472 qdio: Activate the time delay disablement facility.
- Problem-ID: 12700 qeth: Layer 2 network device stalled after cable had been plugged in again.
- Problem-ID: 12247 qeth: add check for HiperSockets on z800/z900.
- Problem-ID: 12549 z90crypt: Timeout running base test.
- Problem-ID: 11023 zfcp: Kernel oops in recovery.
- IBM Code drop 2004-11-02
- Problem-ID: 12107 ctcmpc: Fixes missing channel id (used by chandev) bug and adds additional debug statements.
- Problem-ID: 12026 dasd: FBA error recovery for 3370 and 9336 not called.
- Problem-ID: 12029 dasd: FBA requests failing under memory pressure.
- Problem-ID: 12142 qeth: checksum is generated by stack even with no_checksumming.
- Problem-ID: 12090 qeth: socket write queue is blocked when network cable is pulled.
- Problem-ID: 12175 zfcp: FCP port cannot recover after aborted nameserver request.
- Problem-ID: 11576 zfcp: Insufficient debugging information in /var/log/messages for 'LUN sharing violation'.
- Problem-ID: 12032 zfcp: Kernel panic possible when a timeout handler of a memory pool is called.
- IBM Code drop 2004-10-12
- Add Layer 2 support for OSA-Express to qeth network driver.
- Add z90crypt exploitation of zero-pad function in PCIXCC for the z890/z990 cryptographic cards.
- New ctcmpc device driver for SNA networking - required for using IBM Communications Server for Linux (see Communications Server for Linux on zSeries homepage)
rpm -Fvh k_deflt.rpm zipl
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
