Redhat » Linux : Security Vulnerabilities, CVEs,

Unspecified vulnerability in the kernel in Red Hat Enterprise Linux (RHEL) 4 on the x86_64 platform allows local users to cause a denial of service (OOPS) via unspecified vectors related to the get_gate_vma function and the fuser command.

Memory leak in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ip_cmsg_send function.

Integer overflow in the vc_resize function in the Linux kernel 2.4 and 2.6 before 2.6.10 allows local users to cause a denial of service (kernel crash) via a short new screen value, which leads to a buffer overflow.

/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.

rsync, when running in daemon mode, does not properly call setgroups before dropping privileges, which could provide supplemental group privileges to local users, who could then read certain files that would otherwise be disallowed.

Memory leak in SNMP in Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service.

Vulnerability in (1) pine before 4.33 and (2) the pico editor, included with pine, allows local users local users to overwrite arbitrary files via a symlink attack.

glibc 2.1.9x and earlier does not properly clear the RESOLV_HOST_CONF, HOSTALIASES, or RES_OPTIONS environmental variables when executing setuid/setgid programs, which could allow local users to read arbitrary files.

When using the LD_PRELOAD environmental variable in SUID or SGID applications, glibc does not verify that preloaded libraries in /etc/ld.so.cache are also SUID/SGID, which could allow a local user to overwrite arbitrary files by loading a library from /lib or /usr/lib.

vpop3d program in linuxconf 1.23r and earlier allows local users to overwrite arbitrary files via a symlink attack.

squid 2.3 and earlier allows local users to overwrite arbitrary files via a symlink attack in some configurations.

arpwatch 2.1a4 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

inn 2.2.3 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

privatepw program in wu-ftpd before 2.6.1-6 allows local users to overwrite arbitrary files via a symlink attack.

useradd program in shadow-utils program may allow local users to overwrite arbitrary files via a symlink attack.

getty_ps 2.0.7j allows local users to overwrite arbitrary files via a symlink attack.

rdist 6.1.5 allows local users to overwrite arbitrary files via a symlink attack.

sdiff 2.7 in the diffutils package allows local users to overwrite files via a symlink attack.

gpm 1.19.3 allows local users to overwrite arbitrary files via a symlink attack.

The tmpwatch utility in Red Hat Linux forks a new process for each directory level, which allows local users to cause a denial of service by creating deeply nested directories in /tmp or /var/tmp/.

Linux tmpwatch --fuser option allows local users to execute arbitrary commands by creating files whose names contain shell metacharacters.

Vulnerability in Mandrake Linux usermode package allows local users to to reboot or halt the system.

Linux gpm program allows local users to cause a denial of service by flooding the /dev/gpmctl device with STREAM sockets.

Linux OpenLDAP server allows local users to modify arbitrary files via a symlink attack.

X fontserver xfs allows local users to cause a denial of service via malformed input to the server.
