Redhat » Enterprise Linux : Security Vulnerabilities, CVEs, Published In 2007 (Denial of service)

Red Hat Enterprise Linux 5 and Fedora install the Bind /etc/rndc.key file with world-readable permissions, which allows local users to perform unauthorized named commands, such as causing a denial of service by stopping named.

Memory leak in the Red Hat Content Accelerator kernel patch in Red Hat Enterprise Linux (RHEL) 4 and 5 allows local users to cause a denial of service (memory consumption) via a large number of open requests involving O_ATOMICLOOKUP.

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.

Unspecified vulnerability in the "stack unwinder fixes" in kernel in Red Hat Enterprise Linux 5, when running on AMD64 and Intel 64, allows local users to cause a denial of service via unknown vectors.

mm/mmap.c in the hugetlb kernel, when run on PowerPC systems, does not prevent stack expansion from entering into reserved kernel page memory, which allows local users to cause a denial of service (OOPS) via unspecified vectors.

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.

usr/mgmt_ipc.c in iscsid in open-iscsi (iscsi-initiator-utils) before 2.0-865 checks the client's UID on the listening AF_LOCAL socket instead of the new connection, which allows remote attackers to access the management interface and cause a denial of service (iscsid exit or iSCSI connection loss).

Format string vulnerability in GnomeMeeting 1.0.2 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format strings in the name, which is not properly handled in a call to the gnomemeeting_log_insert function.

The Linux kernel before 2.6.9-42.0.8 in Red Hat 4.4 allows local users to cause a denial of service (kernel OOPS from null dereference) via fput in a 32-bit ioctl on 64-bit x86 systems, an incomplete fix of CVE-2005-3044.1.

The utrace support in Linux kernel 2.6.18, and other versions, allows local users to cause a denial of service (system hang) related to "MT exec + utrace_attach spin failure mode," as demonstrated by ptrace-thrash.c.

The file watch implementation in the audit subsystem (auditctl -w) in the Red Hat Enterprise Linux (RHEL) 4 kernel 2.6.9 allows local users to cause a denial of service (kernel panic) by replacing a watched file, which does not cause the watch on the old inode to be dropped.

Perl-Compatible Regular Expression (PCRE) library before 6.7 does not properly calculate the compiled memory allocation for regular expressions that involve a quantified "subpattern containing a named recursion or subroutine reference," which allows context-dependent attackers to cause a denial of service (error or crash).

Unspecified vulnerability in the listxattr system call in Linux kernel, when a "bad inode" is present, allows local users to cause a denial of service (data corruption) and possibly gain privileges via unknown vectors.
