  • CVE-2004-0394

    A buffer overflow in the panic handling code has been found.

  • CVE-2004-0447

    A local denial of service vulnerability through a null pointer dereference in the IA64 process handling code has been found.

  • CVE-2004-0554

    A local denial of service vulnerability through an infinite loop in the signal handler code has been found.

  • CVE-2004-0565

    An information leak in the context switch code has been found on the IA64 architecture.

  • CVE-2004-0685

    Unsafe use of copy_to_user in USB drivers may disclose sensitive information.

  • CVE-2005-0001

    A race condition in the i386 page fault handler may allow privilege escalation.

  • CVE-2004-0883

    Multiple vulnerabilities in the SMB filesystem code may allow denial of service or information disclosure.

  • CVE-2004-0949

    An information leak discovered in the SMB filesystem code.

  • CVE-2004-1016

    A local denial of service vulnerability has been found in the SCM layer.

  • CVE-2004-1333

    An integer overflow in the terminal code may allow a local denial of service vulnerability.

  • CVE-2004-0997

    A local privilege escalation in the MIPS assembly code has been found.

  • CVE-2004-1335

    A memory leak in the ip_options_get() function may lead to denial of service.

  • CVE-2004-1017

    Multiple overflows exist in the io_edgeport driver which might be usable as a denial of service attack vector.

  • CVE-2005-0124

    Bryan Fulton reported a bounds checking bug in the coda_pioctl function which may allow local users to execute arbitrary code or trigger a denial of service attack.

  • CVE-2003-0984

    Inproper initialization of the RTC may disclose information.

  • CVE-2004-1070

    Insufficient input sanitising in the load_elf_binary() function may lead to privilege escalation.

  • CVE-2004-1071

    Incorrect error handling in the binfmt_elf loader may lead to privilege escalation.

  • CVE-2004-1072

    A buffer overflow in the binfmt_elf loader may lead to privilege escalation or denial of service.

  • CVE-2004-1073

    The open_exec function may disclose information.

  • CVE-2004-1074

    The binfmt code is vulnerable to denial of service through malformed a.out binaries.

  • CVE-2004-0138

    A denial of service vulnerability in the ELF loader has been found.

  • CVE-2004-1068

    A programming error in the unix_dgram_recvmsg() function may lead to privilege escalation.

  • CVE-2004-1234

    The ELF loader is vulnerable to denial of service through malformed binaries.

  • CVE-2005-0003

    Crafted ELF binaries may lead to privilege escalation, due to insufficient checking of overlapping memory regions.

  • CVE-2004-1235

    A race condition in the load_elf_library() and binfmt_aout() functions may allow privilege escalation.

  • CVE-2005-0504
