-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : kernel SUMMARY : Fixes for kernel vulnerabilities DATE : 2004-07-15 11:28:00 ID : CLA-2004:846 RELEVANT RELEASES : 8, 9 - ------------------------------------------------------------------------- DESCRIPTION The Linux kernel is responsible for handling the basic functions of the GNU/Linux operating system. This announcement fixes the following vulnerabilities: 1. Vicam USB driver denial of service (CAN-2004-0075[1]) The Linux kernel Vicam USB driver used an insecure method for copying data from userspace instead of using the copy_from_user function. A local attacker could exploit this vulnerability[1] to possibly cause a denial of service. 2. OSS denial of service (CAN-2004-0178[2]) The OSS code for the Sound Blaster driver in Linux 2.4.x does not properly handle certain sample sizes, which allows local users to cause a denial of service. 3. ISO-9660 buffer overflow vulnerability[3] (CAN-2004-0109[4]) The Linux kernel performs no length checking on symbolic links stored on an ISO9660 file system, allowing a malformed CD to cause an arbitrary length overflow in kernel memory. 4. R128 DRI local privileges escalation (CAN-2004-0003[5]) Alan Cox found a vulnerability in the R128 DRI driver which could potentially lead an attacker to gain unauthorized privileges. 5. do_fork memory leak (CAN-2004-0427[6]) John Byrne found[7] an issue in the do_fork function under certain conditions would not free allocated memory, possibly causing a denial of service. 6. Infoleak on filesystems (CAN-2004-0133[8], CAN-2004-0177[9]) Solar Designer noticed that the ext3[8] code in Linux 2.4.x does not properly initialize journal descriptor blocks, which causes an information leak. In-memory data is written to the device for an ext3 file system, which would allow privileged users to obtain portions of kernel memory by reading the raw device. Chris noticed that it affected JFS too. 7. Buffer overflow at panic state (CAN-2004-0394[10]) The Linux kernel 2.4.x has a buffer overflow in the panic() function, which, at this time, is believed to not be exploitable due to the way panic() works. 8. Sparse bugs (CAN-2004-0495[11]) This announcement adds missing parts of the sparse corrections done to the Linux kernel in our previous announcement[12]. SOLUTION It is recommended that all Conectiva Linux users upgrade the kernel package. IMPORTANT: exercise caution and preparation when upgrading the kernel, since it will require a reboot after the new packages are installed. In particular, Conectiva Linux 9 will most likely require an initrd file (which is automatically created in the /boot directory after the new packages are installed). Generic kernel update instructions can be obtained in the manuals and in our updates page[13]. More detailed instructions are also available in Portuguese at our Moin[14] page.
