| description | A number of vulnerabilities have been discovered in the Linux kernel. - CAN-2003-0461: /proc/tty/driver/serial in Linux 2.4.x reveals the exact number of characters used in serial links, which could allow local users to obtain potentially sensitive information such as the length of passwords. This bug has been fixed by restricting access to /proc/tty/driver/serial. - CAN-2003-0462: A race condition in the way env_start and env_end pointers are initialized in the execve system call and used in fs/proc/base.c on Linux 2.4 allows local users to cause a denial of service (crash). - CAN-2003-0476: The execve system call in Linux 2.4.x records the file descriptor of the executable process in the file table of the calling process, which allows local users to gain read access to restricted file descriptors. - CAN-2003-0501: The /proc filesystem in Linux allows local users to obtain sensitive information by opening various entries in /proc/self before executing a setuid program, which causes the program to fail to change the ownership and permissions of those entries. - CAN-2003-0550: The STP protocol, as enabled in Linux 2.4.x, does not provide sufficient security by design, which allows attackers to modify the bridge topology. This bug has been fixed by disabling STP by default. - CAN-2003-0551: The STP protocol, as enabled in Linux 2.4.x, does not provide sufficient security by design, which allows attackers to modify the bridge topology. - CAN-2003-0552: Linux 2.4.x allows remote attackers to spoof the bridge forwarding table via forged packets whose source addresses are the same as the target. - CAN-2003-0018: Linux kernel 2.4.10 through 2.4.21-pre4 does not properly handle the O_DIRECT feature, which allows local attackers with write privileges to read portions of previously deleted files, or cause file system corruption. This bug has been fixed by disabling O_DIRECT. - CAN-2003-0619: Integer signedness error in the decode_fh function of nfs3xdr.c in Linux kernel before 2.4.21 allows remote attackers to cause a denial of service (kernel panic) via a negative size value within XDR data of an NFSv3 procedure call. This advisory covers only the i386 and alpha architectures. Other architectures will be covered by separate advisories. |
