Weekly Vulnerabilities Reports > December 20 to 26, 2004

Format string vulnerability in SHOUTcast 1.9.4 allows remote attackers to cause a denial of service (application crash) and execute arbitrary code via format string specifiers in a content URL, as demonstrated in the filename portion of a .mp3 file.

Format string vulnerability in telnetd-ssl 0.17 and earlier allows remote attackers to execute arbitrary code.

Apple iChat AV 2.1, AV 2.0, and 1.0.1 allows remote attackers to execute arbitrary programs via a "link" that references the program.

Mozilla Firefox 0.9.2 allows web sites to set cookies for country-specific top-level domains, such as .ltd.uk, .plc.uk, and .sch.uk, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session.

Sendmail before 8.12.3 on Debian GNU/Linux, when using sasl and sasl-bin, uses a Sendmail configuration script with a fixed username and password, which could allow remote attackers to use Sendmail as an open mail relay and send spam messages.

Integer underflow in the firewall logging rules for iptables in Linux before 2.6.8 allows remote attackers to cause a denial of service (application crash) via a malformed IP packet.

Buffer overflow in layer2.c in mpg123 0.59r and possibly mpg123 0.59s allows remote attackers to execute arbitrary code via a certain (1) mp3 or (2) mp2 file.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files.

distcc before 2.16, when running on 64-bit platforms, does not interpret IP-based access control rules correctly, which could allow remote attackers to bypass intended restrictions.

Stack-based buffer overflow in the comprexx function for ncompress 4.2.4 and earlier, when used in situations that cross security boundaries (such as FTP server), may allow remote attackers to execute arbitrary code via a long filename argument.

Buffer overflow in htget 0.93 allows remote attackers to execute arbitrary code via a crafted URL.

Star before 1.5_alpha46 does not drop the effective user ID (euid) before calling external programs, which could allow local users to gain privileges by modifying the RSH environment variable to reference a malicious program.

Untrusted execution path vulnerability in the diag commands (1) lsmcode, (2) diag_exec, (3) invscout, and (4) invscoutd in AIX 5.1 through 5.3 allows local users to execute arbitrary programs by modifying the DIAGNOSTICS environment variable to point to a malicious Dctrl program.

Buffer overflow in dxterm in Ultrix 4.5 allows local users to execute arbitrary code via a long -setup parameter.

Multiple cross-site scripting (XSS) vulnerabilities in Phpgroupware (aka webdistro) 0.9.16.002 and earlier allow remote attackers to insert arbitrary HTML or web script, as demonstrated with a request to the wiki module.

SQL injection vulnerability in the (1) MDSYS.SDO_GEOM_TRIG_INS1 and (2) MDSYS.SDO_LRS_TRIG_INS default triggers in Oracle 9i and 10g allows remote attackers to execute arbitrary SQL commands via the new.table_name or new.column_name parameters.

The triggers in Oracle 9i and 10g allow local users to gain privileges by using a sequence of partially privileged actions: using CCBKAPPLROWTRIG or EXEC_CBK_FN_DML to add arbitrary functions to the SDO_CMT_DBK_FN_TABLE and SDO_CMT_CBK_DML_TABLE, then performing a DELETE on the SDO_TXN_IDX_INSERTS table, which causes the SDO_CMT_CBK_TRIG trigger to execute the user-supplied functions.

Integer underflow in winhlp32.exe in Windows NT, Windows 2000 through SP4, Windows XP through SP2, and Windows 2003 allows remote attackers to execute arbitrary code via a malformed .hlp file, which leads to a heap-based buffer overflow.

Integer overflow in the asn_decode_string() function defined in asn1.c in radiusd for GNU Radius 1.1 and 1.2 before 1.2.94, when compiled with the --enable-snmp option, allows remote attackers to cause a denial of service (daemon crash) via certain SNMP requests.

Buffer overflow in Netopia Timbuktu 7.0.3 allows remote attackers to cause a denial of service (server process crash) via a certain data string that is sent to multiple simultaneous client connections to TCP port 407.

The mod_authz_svn module in Subversion 1.0.7 and earlier does not properly restrict access to all metadata on unreadable paths, which could allow remote attackers to gain sensitive information via (1) svn log -v, (2) svn propget, or (3) svn blame, and other commands that follow renames.

The original design of ICMP does not require authentication for host-generated ICMP error messages, which makes it easier for attackers to forge ICMP error messages for specific TCP connections and cause a denial of service, as demonstrated using (1) blind connection-reset attacks with forged "Destination Unreachable" messages, (2) blind throughput-reduction attacks with forged "Source Quench" messages, or (3) blind throughput-reduction attacks with forged ICMP messages that cause the Path MTU to be reduced.

The original design of TCP does not require that port numbers be assigned randomly (aka "Port randomization"), which makes it easier for attackers to forge ICMP error messages for specific TCP connections and cause a denial of service, as demonstrated using (1) blind connection-reset attacks with forged "Destination Unreachable" messages, (2) blind throughput-reduction attacks with forged "Source Quench" messages, or (3) blind throughput-reduction attacks with forged ICMP messages that cause the Path MTU to be reduced.

The original design of TCP does not check that the TCP Acknowledgement number in an ICMP error message generated by an intermediate router is within the range of possible values for data that has already been acknowledged (aka "TCP acknowledgement number checking"), which makes it easier for attackers to forge ICMP error messages for specific TCP connections and cause a denial of service, as demonstrated using (1) blind connection-reset attacks with forged "Destination Unreachable" messages, (2) blind throughput-reduction attacks with forged "Source Quench" messages, or (3) blind throughput-reduction attacks with forged ICMP messages that cause the Path MTU to be reduced.

Unknown vulnerability in System Administration Manager (SAM) in HP-UX B.11.00, B.11.11, B.11.22, and B.11.23 allows local users to gain privileges.

Certain USB drivers in the Linux 2.4 kernel use the copy_to_user function on uninitialized structures, which could allow local users to obtain sensitive information by reading memory that was not cleared from previous usage.

Skype 0.92.0.12 and 1.0.0.1 for Linux, and possibly other versions, creates the /usr/share/skype/lang directory with world-writable permissions, which allows local users to modify language files and possibly conduct social engineering or other attacks.

Multiple cross-site scripting (XSS) vulnerabilities in privmsg.php in phpBB 2.0.6 allow remote attackers to execute arbitrary script or HTML via the (1) folder or (2) mode variables.

Race condition in the rmtree function in the File::Path module in Perl 5.6.1 and 5.8.4 sets read/write permissions for the world, which allows local users to delete arbitrary files and directories, and possibly read files and directories, via a symlink attack.

The tspc.conf configuration file in freenet6 before 0.9.6 and before 1.0 on Debian Linux has world readable permissions, which could allow local users to gain sensitive information, such as a username and password.

Multiple unknown vulnerabilities in MMDF on OpenServer 5.0.6 and 5.0.7, and possibly other operating systems, may allow attackers to cause a denial of service by triggering a core dump.

Multiple unknown vulnerabilities in MMDF on OpenServer 5.0.6 and 5.0.7, and possibly other operating systems, may allow attackers to cause a denial of service by triggering a null dereference.
