RealtimeKit is a D-Bus system service that changes the scheduling policy of user processes/threads to SCHED_RR on request. It is intended to be used as a secure mechanism to allow real-time scheduling to be used by normal user processes. It was found that RealtimeKit communicated with PolicyKit for authorization using a D-Bus API that is vulnerable to a race condition. This could have led to inte ...

The libtar package contains a C library for manipulating tar archives. The library supports both the strict POSIX tar format and many of the commonly used GNU extensions. Two heap-based buffer overflow flaws were found in the way libtar handled certain archives. If a user were tricked into expanding a specially-crafted archive, it could cause the libtar executable or an application using libtar to ...

gc is a Boehm-Demers-Weiser conservative garbage collector for C and C++. It was discovered that gc"s implementation of the malloc and calloc routines did not properly perform parameter sanitization when allocating memory. If an application using gc did not implement application-level validity checks for the malloc and calloc routines, a remote attacker could provide specially crafted application- ...

OpenJPEG is an open source library for reading and writing image files in JPEG 2000 format. Multiple heap-based buffer overflow flaws were found in OpenJPEG. An attacker could create a specially crafted OpenJPEG image that, when opened, could cause an application using openjpeg to crash or, possibly, execute arbitrary code with the privileges of the user running the application. Multiple denial o ...

Pixman is a pixel manipulation library for the X Window System and Cairo. An integer overflow, which led to a heap-based buffer overflow, was found in the way pixman handled trapezoids. If a remote attacker could trick an application using pixman into rendering a trapezoid shape with specially crafted coordinates, it could cause the application to crash or, possibly, execute arbitrary code with th ...

Augeas is a utility for editing configuration. Augeas parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files. Augeas also uses "lenses" as basic building blocks for establishing the mapping from files into the Augeas tree and back. A flaw was found in t ...

The librsvg2 packages provide an SVG library based on libart. An XML External Entity expansion flaw was found in the way librsvg2 processed SVG files. If a user were to open a malicious SVG file, a remote attacker could possibly obtain a copy of the local resources that the user had access to. All librsvg2 users are advised to upgrade to these updated packages, which contain a backported patch t ...

Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. A heap-based buffer overflow flaw was found in the way Pidgin processed certain HTTP responses. A malicious server could send a specially crafted HTTP response, causing Pidgin to crash or potentially execute arbitrary code with the permissions of the user running Pidg ...

The wget package provides the GNU Wget file retrieval utility for HTTP, HTTPS, and FTP protocols. Wget provides various useful features, such as the ability to work in the background while the user is logged out, recursive retrieval of directories, file name wildcard matching or updating files in dependency on file timestamp comparison. It was discovered that wget used a file name provided by the ...

Mutt is a text-mode mail user agent. A heap-based buffer overflow flaw was found in the way mutt processed certain email headers. A remote attacker could use this flaw to send an email with specially crafted headers that, when processed, could cause mutt to crash or, potentially, execute arbitrary code with the permissions of the user running mutt. All mutt users are advised to upgrade to this up ...
