Weekly Vulnerabilities Reports > December 15 to 21, 2003

NFS Server (XNFS.NLM) for Novell NetWare 6.5 does not properly enforce sys:\etc\exports when hostname aliases from sys:etc\hosts file are used, which could allow users to mount file systems when XNFS should deny the host.

eo420_GetStringFromVarPart in veo420.c for SAP database server (SAP DB) 7.4.03.27 and earlier may allow remote attackers to execute arbitrary code via a connect packet with a 256 byte segment to the niserver (aka serv.exe) process on TCP port 7269, which prevents the server from NULL terminating the string and leads to a buffer overflow.

Buffer overflow in the debug functionality in fp30reg.dll of Microsoft FrontPage Server Extensions (FPSE) 2000 and 2002 allows remote attackers to execute arbitrary code via a crafted chunked encoded request.

Microsoft Excel 97, 2000, and 2002 allows remote attackers to execute arbitrary code via a spreadsheet with a malicious XLM (Excel 4) macro that bypasses the macro security model.

Microsoft Word 97, 98(J), 2000, and 2002, and Microsoft Works Suites 2001 through 2004, do not properly check the length of the "Macro names" data value, which could allow remote attackers to execute arbitrary code via a buffer overflow attack.

Stack-based buffer overflow in a logging function for Windows Workstation Service (WKSSVC.DLL) allows remote attackers to execute arbitrary code via RPC calls that cause long entries to be written to a debug log file ("NetSetup.LOG"), as demonstrated using the NetAddAlternateComputerName API.

Integer overflow in the do_brk function for the brk system call in Linux kernel 2.4.22 and earlier allows local users to gain root privileges.

Buffer overflow in iwconfig allows local users to execute arbitrary code via a long HOME environment variable.

Buffer overflow in iwconfig, when installed setuid, allows local users to execute arbitrary code via a long OUT environment variable.

vos24u.c in SAP database server (SAP DB) 7.4.03.27 and earlier allows local users to gain SYSTEM privileges via a malicious "NETAPI32.DLL" in the current working directory, which is found and loaded by SAP DB before the real DLL, as demonstrated using the SQLAT stored procedure.

Symantec PCAnywhere 10.x and 11, when started as a service, allows attackers to gain SYSTEM privileges via the help interface using AWHOST32.exe.

Buffer overflow in the Software Distributor utilities for HP-UX B.11.00 and B.11.11 allows local users to execute arbitrary code via a long LANG environment variable to setuid programs such as (1) swinstall and (2) swmodify.

Apple Safari 1.0 through 1.1 on Mac OS X 10.3.1 and Mac OS X 10.2.8 allows remote attackers to steal user cookies from another domain via a link with a hex-encoded null character (%00) followed by the target domain.

Unknown vulnerability in mod_python 3.0.x before 3.0.4, and 2.7.x before 2.7.9, allows remote attackers to cause a denial of service (httpd crash) via a certain query string.

GnuPG (GPG) 1.0.2, and other versions up to 1.2.3, creates ElGamal type 20 (sign+encrypt) keys using the same key component for encryption as for signing, which allows attackers to determine the private key from a signature.

The Network Management Port on Sun Fire B1600 systems allows remote attackers to cause a denial of service (packet loss) via ARP packets, which cause all ports to become temporarily disabled.

rad_decode in FreeRADIUS 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a short RADIUS string attribute with a tag, which causes memcpy to be called with a -1 length argument, as demonstrated using the Tunnel-Password attribute.

Directory traversal vulnerability in sqlfopenc for web-tools in SAP DB before 7.4.03.30 allows remote attackers to read arbitrary files via ..

Unknown vulnerability in the SmartHTML interpreter (shtml.dll) in Microsoft FrontPage Server Extensions 2000 and 2002, and Microsoft SharePoint Team Services 2002, allows remote attackers to cause a denial of service (response failure) via a certain request.

The vty layer in Quagga before 0.96.4, and Zebra 0.93b and earlier, does not verify that sub-negotiation is taking place when processing the SE marker, which allows remote attackers to cause a denial of service (crash) via a malformed telnet command to the telnet CLI port, which may trigger a null dereference.

PeopleSoft Gateway Administration servlet (gateway.administration) in PeopleTools 8.43 and earlier allows remote attackers to obtain the full pathnames for server-side include (SSI) files via an HTTP request with an invalid value.

Sybase Adaptive Server Enterprise (ASE) 12.5 allows remote attackers to cause a denial of service (hang) via a remote password array with an invalid length, which triggers a heap-based buffer overflow.

iproute 2.4.7 and earlier allows local users to cause a denial of service via spoofed messages as other users to the kernel netlink interface.

OpenBSD kernel 3.3 and 3.4 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code in 3.4 via a program with an invalid header that is not properly handled by (1) ibcs2_exec.c in the iBCS2 emulation (compat_ibcs2) or (2) exec_elf.c, which leads to a stack-based buffer overflow.

Buffer overflow in omega-rpg 0.90 allows local users to execute arbitrary code via a long (1) command line or (2) environment variable.

Zebra 0.93b and earlier, and quagga before 0.95, allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.
