Security

Format string vulnerability in the AbstractCommand::onAbort function in src/AbstractCommand.cc in aria2 before 1.6.2, when logging is enabled, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via format string specifiers in a download URI. NOTE: some of these details are obtained from third party information.

A vulnerability have been discovered in Mandriva bash package, which could allow a malicious user to hide files from the ls command, or garble its output by crafting files or directories which contain special characters or escape sequences (CVE-2010-0002). This update fixes the issue by disabling the display of control characters by default.

Additionally, this update fixes the unsafe file creation in bash-doc sample scripts (CVE-2008-5374).

From the Red Hat advisory:

A flaw was found in the BIND DNSSEC NSEC/NSEC3 validation code. If BIND was running as a DNSSEC-validating resolver, it could incorrectly cache NXDOMAIN responses, as if they were valid, for records proven by NSEC or NSEC3 to exist. A remote attacker could use this flaw to cause a BIND server to return the bogus, cached NXDOMAIN responses for valid records and prevent users from retrieving those records (denial of service). (CVE-2010-0097)

The original fix for CVE-2009-4022 was found to be incomplete. BIND was incorrectly caching certain responses without performing proper DNSSEC validation. CNAME and DNAME records could be cached, without proper DNSSEC validation, when received from processing recursive client queries that requested DNSSEC records but indicated that checking should be disabled. A remote attacker could use this flaw to bypass the DNSSEC validation check and perform a cache poisoning attack if the target BIND server was receiving such client queries. (CVE-2010-0290)

A flaw was found in the way GNU Libtool's libltdl library looked for libraries to load. It was possible for libltdl to load a malicious library from the current working directory. In certain configurations, if a local attacker is able to trick a local user into running a Java application (which uses a function to load native libraries, such as System.loadLibrary) from within an attacker-controlled directory containing a malicious library or module, the attacker could possibly execute arbitrary code with the privileges of the user running the Java application.

From the Debian advisory:

Christoph Pleger has discovered that the GNU C Library (aka glibc) and its derivatives add information from the passwd.adjunct.byname map to entries in the passwd map, which allows local users to obtain the encrypted passwords of NIS accounts by calling the getpwnam function.

From the Debian advisory:

Thiemo Nagel discovered a missing input sanitation flaw in the way gzip used to decompress data blocks for dynamic Huffman codes, which could lead to the execution of arbitrary code when trying to decompress a crafted archive. This issue is a reappearance of CVE-2006-4334 and only affects the lenny version.

From the Red Hat advisory:

An integer underflow flaw, leading to an array index error, was found in the way gzip expanded archive files compressed with the Lempel-Ziv-Welch (LZW) compression algorithm. If a victim expanded a specially-crafted archive, it could cause gzip to crash or, potentially, execute arbitrary code with the privileges of the user running gzip. This flaw only affects 64-bit systems. (CVE-2010-0001)

From the Red Hat advisory:

the RHSA-2009:0225 update introduced a rewrite attack flaw in the do_coredump() function. A local attacker able to guess the file name a process is going to dump its core to, prior to the process crashing, could use this flaw to append data to the dumped core file. This issue only affects systems that have "/proc/sys/fs/suid_dumpable" set to 2 (the default value is 0). (CVE-2006-6304, Moderate)

The fix for CVE-2006-6304 changes the expected behavior: With suid_dumpable set to 2, the core file will not be recorded if the file already exists. For example, core files will not be overwritten on subsequent crashes of processes whose core files map to the same name.

the RHBA-2008:0314 update introduced N_Port ID Virtualization (NPIV) support in the qla2xxx driver, resulting in two new sysfs pseudo files, "/sys/class/scsi_host/[a qla2xxx host]/vport_create" and "vport_delete". These two files were world-writable by default, allowing a local user to change SCSI host attributes. This flaw only affects systems using the qla2xxx driver and NPIV capable hardware. (CVE-2009-3556, Moderate)

a buffer overflow flaw was found in the hfs_bnode_read() function in the HFS file system implementation. This could lead to a denial of service if a user browsed a specially-crafted HFS file system, for example, by running "ls". (CVE-2009-4020, Low)

Tavis Ormandy discovered a deficiency in the fasync_helper() implementation. This could allow a local, unprivileged user to leverage a use-after-free of locked, asynchronous file descriptors to cause a denial of service or privilege escalation. (CVE-2009-4141, Important)

the Parallels Virtuozzo Containers team reported the RHSA-2009:1243 update introduced two flaws in the routing implementation. If an attacker was able to cause a large enough number of collisions in the routing hash table (via specially-crafted packets) for the emergency route flush to trigger, a deadlock could occur. Secondly, if the kernel routing cache was disabled, an uninitialized pointer would be left behind after a route lookup, leading to a kernel panic. (CVE-2009-4272, Important)

From the Mandriva advisory:

The vio_verify_callback function in viosslfactories.c in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41, when OpenSSL is used, accepts a value of zero for the depth of X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL-based MySQL servers via a crafted certificate, as demonstrated by a certificate presented by a server linked against the yaSSL library (CVE-2009-4028).

MySQL 5.1.x before 5.1.41 allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4098 and CVE-2008-2079 (CVE-2009-4030).

It was discovered that a significant memory leak could occur in openssl, related to the reinitialization of zlib. This could result in a remotely exploitable denial of service vulnerability when using the Apache httpd server in a configuration where mod_ssl, mod_php5, and the php5-curl extension are loaded.

From the Mandriva advisory:

libraries/File.class.php in phpMyAdmin 2.11.x before 2.11.10 creates a temporary directory with 0777 permissions, which has unknown impact and attack vectors (CVE-2008-7251).

libraries/File.class.php in phpMyAdmin 2.11.x before 2.11.10 uses predictable filenames for temporary files, which has unknown impact and attack vectors (CVE-2008-7252).

scripts/setup.php (aka the setup script) in phpMyAdmin 2.11.x before 2.11.10 calls the unserialize function on the values of the (1) configuration and (2) v[0] parameters, which might allow remote attackers to conduct cross-site request forgery (CSRF) attacks via unspecified vectors (CVE-2009-4605).

From the Zend Framework release notes for 1.97:

The following security vulnerabilities are resolved in these releases:

• ZF2010-06: Potential XSS or HTML Injection vector in Zend_Json
• ZF2010-05: Potential XSS vector in Zend_Service_ReCaptcha_MailHide
• ZF2010-04: Potential MIME-type Injection in Zend_File_Transfer
• ZF2010-03: Potential XSS vector in Zend_Filter_StripTags when comments allowed
• ZF2010-02: Potential XSS vector in Zend_Dojo_View_Helper_Editor
• ZF2010-01: Potential XSS vectors due to inconsistent encodings

A security vulnerability is found on WEBrick module in Ruby currently shipped on Fedora 11 that WEBrick lets attackers to inject malicious escape sequences to its logs, making it possible for dangerous control characters to be executed on a victim's terminal emulator.

The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.19-1 on Debian GNU/Linux, and possibly other operating systems and versions, allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program. NOTE: this issue exists because of an incomplete fix for CVE-2009-1579.

From the Red Hat bugzilla entry:

A flaw was found in the "stap-server" network compilation server, an optional part of systemtap. Part of the server is written in bash and does not adequately sanitize its inputs, which are essentially full command line parameter sets from a client. Remote users may be able to abuse quoting/spacing/metacharacters to execute shell code on behalf of the compile server process/user (normally a fully unprivileged synthetic userid).

From the Mandriva advisory:

Cross-site request forgery (CSRF) vulnerability in Transmission 1.5 before 1.53 and 1.6 before 1.61 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors (CVE-2009-1757).

* A shell metacharacter injection in popen() (CVE-2009-3692) and a possible buffer overflow in strncpy() in the VBoxNetAdpCtl configuration tool. * An unspecified vulnerability in VirtualBox Guest Additions (CVE-2009-3940).
