Security

From the Slackware advisory:

Patched to fix a security flaw in the file-local variables code. When the Emacs user option `enable-local-variables' is set to `:safe' (the default value is t), Emacs should automatically refuse to evaluate `eval' forms in file-local variable sections. Due to the bug, Emacs instead automatically evaluates such `eval' forms. Thus, if the user changes the value of `enable-local-variables' to `:safe', visiting a malicious file can cause automatic execution of arbitrary Emacs Lisp code with the permissions of the user. Bug discovered by Paul Ling.

From the Red Hat advisory:

Specially-crafted SWF content could cause flash-plugin to crash or, potentially, execute arbitrary code when a victim loads a page containing the malicious SWF content. (CVE-2012-1535)

From the Red Hat advisory:

It was discovered the the GNU Debugger (gdb) would load untrusted files from the current working directory when .debug_gdb_scripts was defined. While this was a design decision, it is an insecure one and users who do not pre-inspect untrusted files may execute arbitrary code with their privileges.

A heap-based buffer overflow flaw was found in the GIMP's KiSS CEL file format plug-in. An attacker could create a specially-crafted KiSS palette file that, when opened, could cause the CEL plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP. (CVE-2012-3403)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the GIMP's GIF image format plug-in. An attacker could create a specially-crafted GIF image file that, when opened, could cause the GIF plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP. (CVE-2012-3481)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in the GIMP's Adobe Photoshop (PSD) image file plug-in. An attacker could create a specially-crafted PSD image file that, when opened, could cause the PSD plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP. (CVE-2009-3909, CVE-2012-3402)

Multiple integer overflows, leading to stack-based buffer overflows were found in various stdlib functions of GNU libc (strtod, strtof, strtold, strtod_l and related routines). If an application, using the affected stdlib functions, did not perform user-level sanitization of provided inputs, a local attacker could use this flaw to cause such an application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

From the Mandriva advisory:

Multiple cross-site request forgery (CSRF) and cross-site scripting (XSS) flaws has been found and corrected in GLPI (CVE-2012-4002, CVE-2012-4003).

Tom Lane discovered that ImageMagick would not always properly allocate memory. If a user or automated system using ImageMagick were tricked into opening a specially crafted PNG image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.

Sébastien Bocahu discovered that the reverse proxy add forward module for the Apache webserver is vulnerable to a denial of service attack through a single crafted request with many headers.

virt/disk/api.py in OpenStack Compute (Nova) 2012.1.x before 2012.1.2 and Folsom before Folsom-3 allows remote authenticated users to overwrite arbitrary files via a symlink attack on a file in an image that uses a symlink that is only readable by root. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3361.

[1] Florian Weimer of the Red Hat Product Security Team discovered multiple integer and heap-based buffer overflow flaws in PCP (Performance Co-Pilot) libpcp protocol decoding functions. These flaws could lead to daemon crashes or the execution of arbitrary code with root privileges. Many of these flaws can be exploited without requiring the attacker to be authenticated. (CVE-2012-3418)

[2] Florian Weimer of the Red Hat Product Security Team discovered that pmcd (the PCP (Performance Co-Pilot) performance metrics collector daemon) exports part of the /proc file system, including privileged information that could be used to aid in bypassing ASLR, as well as full commandline information on running programs. (CVE-2012-3419)

[3] Florian Weimer of the Red Hat Product Security Team discovered two memory leaks in libpcp that can be abused by an unauthenticated remote attacker to crash pmcd (the PCP (Performance Co-Pilot) performance metrics collector daemon) or to consume enough memory to trigger the OOM killer, which may have impact on other processes. (CVE-2012-3420)

[4] Florian Weimer of the Red Hat Product Security Team discovered a denial of service flaw in pmcd (the PCP (Performance Co-Pilot) performance metrics collector daemon) due to incorrect event-driven programming. Because the pduread() function in libpcp performs a select locally, waiting for more client data, an unauthenticated remote attacker could send individual bytes one by one, avoiding the timeout, and blocking pmcd in order to prevent it from responding to other legitimate requests. (CVE-2012-3421)

From the phpMyAdmin advisory:

Using a crafted table name, it was possible to produce a XSS : 1) On the Database Structure page, creating a new table with a crafted name 2) On the Database Structure page, using the Empty and Drop links of the crafted table name 3) On the Table Operations page of a crafted table, using the 'Empty the table (TRUNCATE)' and 'Delete the table (DROP)' links 4) On the Triggers page of a database containing tables with a crafted name, when opening the 'Add Trigger' popup 5) When creating a trigger for a table with a crafted name, with an invalid definition. Having crafted data in a database table, it was possible to produce a XSS : 6) When visualizing GIS data, having a crafted label name.

This security release fixes a vulnerability in the built-in XML functionality, and a vulnerability in the XSLT functionality supplied by the optional XML2 extension. Both vulnerabilities allow reading of arbitrary files by any authenticated database user, and the XSLT vulnerability allows writing files as well. The fixes cause limited backwards compatibility issues.

A flaw was found in the way Red Eclipse handled config files. In cube2-engine games, game maps can be transmitted either from the server to a client, or from client to client. These maps include a config file (mapname.cfg) in "cubescript" format, which allows for an attacker to send a malicious script via a new map. This map must either be chosen by an administrator on the server, or created in co-operative editing mode. A malicious script could then be used to read or write to any files that the user running the client has access to when the victim loads a map with the malicious configuration file.

From the Debian advisory:

Henrik Erkkonen discovered that rssh, a restricted shell for SSH, does not properly restrict shell access.

From the Mandriva advisory:

Multiple vulnerabilities was found and corrected in Wireshark:

The DCP ETSI dissector could trigger a zero division (CVE-2012-4285).

The MongoDB dissector could go into a large loop (CVE-2012-4287).

The XTP dissector could go into an infinite loop (CVE-2012-4288).

The AFP dissector could go into a large loop (CVE-2012-4289).

The RTPS2 dissector could overflow a buffer (CVE-2012-4296).

The GSM RLC MAC dissector could overflow a buffer (CVE-2012-4297).

The CIP dissector could exhaust system memory (CVE-2012-4291).

The STUN dissector could crash (CVE-2012-4292).

The EtherCAT Mailbox dissector could abort (CVE-2012-4293).

The CTDB dissector could go into a large loop (CVE-2012-4290).

A guest kernel can cause the host to become unresponsive for a period of time, potentially leading to a DoS. Since an attacker with full control in the guest can impact on the host, this vulnerability is consider with high impact.
