Vulnerabilities (CVE)

The bluez_sock_create function in the Bluetooth stack for Linux kernel 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 allows local users to gain privileges via (1) socket or (2) socketpair call with a negative protocol value.

Buffer overflow in University of Washington's implementation of IMAP and POP servers.

Buffer overflow in SGI IRIX mailx program.

The 64 bit ELF support in Linux kernel 2.6 before 2.6.10, on 64-bit architectures, does not properly check for overlapping VMA (virtual memory address) allocations, which allows local users to cause a denial of service (system crash) or execute arbitrary code via a crafted ELF or a.out file.

dumpreg in Red Hat Linux 5.1 opens /dev/mem with O_RDWR access, which allows local users to cause a denial of service (crash) by redirecting fd 1 (stdout) to the kernel.

Buffer overflow in KON kon2 0.3.9b and earlier allows local users to execute arbitrary code via a long -Coding command line argument.

mopd (Maintenance Operations Protocol loader daemon) does not properly cleanse user-injected format strings, which allows remote attackers to execute arbitrary commands.

Multiple unknown vulnerabilities in Linux kernel 2.4 and 2.6 allow local users to gain privileges or access kernel memory, as found by the Sparse source code checking tool.

Multiple heap-based buffer overflows in the imlib BMP image handler allow remote attackers to execute arbitrary code via a crafted BMP file.

init_dev in tty_io.c in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 does not properly clear controlling tty's in multi-threaded applications, which allows local users to cause a denial of service (crash) and possibly gain tty access via unknown attack vectors that trigger an access of a pointer to a freed structure.

crontab in Vixie cron 4.1, when running with the -e option, allows local users to read the cron files of other users by changing the file being edited to a symlink. NOTE: there is insufficient information to know whether this is a duplicate of CVE-2001-0235.

Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users.

cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files.

The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.

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

Format string vulnerability in print_client in icecast 1.3.8beta2 and earlier allows remote attackers to execute arbitrary commands.

A regression error in the Red Hat Enterprise Linux 4 kernel 4GB/4GB split patch omits an "access check," which allows local users to cause a denial of service (crash).

The default configuration of Apache 2.0.40, as shipped with Red Hat Linux 9.0, allows remote attackers to list directory contents, even if auto indexing is turned off and there is a default web page configured, via a GET request containing a double slash (//).

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

restore 0.4b15 and earlier in Red Hat Linux 6.2 trusts the pathname specified by the RSH environmental variable, which allows local users to obtain root privileges by modifying the RSH variable to point to a Trojan horse program.

Arbitrary command execution via metamail package using message headers, when user processes attacker's message using metamail.

lv reads a .lv file from the current working directory, which allows local users to execute arbitrary commands as other lv users by placing malicious .lv files into other directories.

The raw_sendmsg function in the Linux kernel 2.6 before 2.6.13.1 allows local users to cause a denial of service (change hardware state) or read from arbitrary memory via crafted input.

expect before 5.32 searches for its libraries in /var/tmp before other directories, which could allow local users to gain root privileges via a Trojan horse library that is accessed by mkpasswd.

The linux-2.4.21-mlock.patch in Red Hat Enterprise Linux 3 does not properly maintain the mlock page count when one process unlocks pages that belong to another process, which allows local users to mlock more memory than specified by the rlimit.

Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.

Buffer overflow in NLS (Natural Language Service).

dn2ancestor in the LDAP component in Fedora Directory Server 1.0 allows remote attackers to cause a denial of service (CPU and memory consumption) via a ModDN operation with a DN that contains a large number of "," (comma) characters, which results in a large amount of recursion, as demonstrated using the ProtoVer LDAP test suite.

Local users can start Sendmail in daemon mode and gain root privileges.

scan.c for LibXPM may allow attackers to execute arbitrary code via a negative bitmap_unit value that leads to a buffer overflow.

A regression error in the Perl package for Red Hat Enterprise Linux 4 omits the patch for CVE-2005-0155, which allows local users to overwrite arbitrary files with debugging information.

Fedora Directory Server before 10 allows remote attackers to obtain sensitive information, such as the password from adm.conf via an IFRAME element, probably involving an Apache httpd.conf configuration that orders "allow" directives before "deny" directives.

Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as used in XFree86 and other packages, include (1) multiple integer overflows, (2) out-of-bounds memory accesses, (3) directory traversal, (4) shell metacharacter, (5) endless loops, and (6) memory leaks, which could allow remote attackers to obtain sensitive information, cause a denial of service (application crash), or execute arbitrary code via a certain XPM image file. NOTE: it is highly likely that this candidate will be SPLIT into o ...
