Ulf Harnhammar discovered that vim does not properly sanitise the "helptags_one()" function when running the "helptags" command. By tricking a user into running a crafted help file, a remote attacker could execute arbitrary code with the user's privileges.

Ubuntu: tar vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Dmitry V. Levin discovered that tar did not correctly detect the ".." file path element when unpacking archives. If a user or an automated system were tricked into unpacking a specially crafted tar file, arbitrary files could be overwritten with user privileges.

Ubuntu: KDE vulnerabilities

Ubuntu: KDE vulnerabilities

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that Konqueror could be tricked into displaying incorrect URLs. Remote attackers could exploit this to increase their chances of tricking a user into visiting a phishing URL, which could lead to credential theft.

Ubuntu: Thunderbird vulnerabilities USN-503-1

Ubuntu: Thunderbird vulnerabilities USN-503-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Various flaws were discovered in the layout and JavaScript engines. By tricking a user into opening a malicious email, an attacker could execute arbitrary code with the user's privileges. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it.

Ubuntu: jasper vulnerability

Ubuntu: jasper vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that Jasper did not correctly handle corrupted JPEG2000 images. By tricking a user into opening a specially crafted JPG, a remote attacker could cause the application using libjasper to crash, resulting in a denial of service.

Ubuntu: rsync vulnerability USN-500-1

Ubuntu: rsync vulnerability USN-500-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Sebastian Krahmer discovered that rsync contained an off-by-one miscalculation when handling certain file paths. By creating a specially crafted tree of files and tricking an rsync server into processing them, a remote attacker could write a single NULL to stack memory, possibly leading to arbitrary code execution.

Ubuntu: Apache vulnerabilities USN-499-1

Ubuntu: Apache vulnerabilities USN-499-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Stefan Esser discovered that mod_status did not force a character set, which could result in browsers becoming vulnerable to XSS attacks when processing the output. If a user were tricked into viewing server status output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. By default, mod_status is disabled in Ubuntu.

Ubuntu: libvorbis vulnerabilities USN-498-1

Ubuntu: libvorbis vulnerabilities USN-498-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

David Thiel discovered that libvorbis did not correctly verify the size of certain headers, and did not correctly clean up a broken stream. If a user were tricked into processing a specially crafted Vorbis stream, a remote attacker could execute arbitrary code with the user's privileges.

Ubuntu: Qt vulnerability USN-579-1

Ubuntu: Qt vulnerability USN-579-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Several format string vulnerabilities have been discovered in Qt warning messages. By causing an application to process specially crafted input data which triggered Qt warnings, this could be exploited to execute arbitrary code with the privilege of the user running the application.

Ubuntu: Gimp vulnerability

Ubuntu: Gimp vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Sean Larsson discovered multiple integer overflows in Gimp. By tricking a user into opening a specially crafted DICOM, PNM, PSD, PSP, RAS, XBM, or XWD image, a remote attacker could exploit this to execute arbitrary code with the user's privileges.

Ubuntu: Firefox vulnerabilities USN-493-1

Ubuntu: Firefox vulnerabilities USN-493-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A flaw was discovered in handling of "about:blank" windows used by addons. A malicious web site could exploit this to modify the contents, or steal confidential data (such as passwords), of other web pages. Jesper Johansson discovered that spaces and double-quotes were not correctly handled when launching external programs. In rare configurations, after tricking a user into opening a malicious web page, an attacker could execute helpers with arbitrary arguments with the user's privileges.

Ubuntu: Bind vulnerability

Ubuntu: Bind vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A flaw was discovered in Bind's sequence number generator. A remote attacker could calculate future sequence numbers and send forged DNS query responses. This could lead to client connections being directed to attacker-controlled hosts, resulting in credential theft and other attacks.

Ubuntu: redhat-cluster-suite vulnerability

Ubuntu: redhat-cluster-suite vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

USN-489-1 fixed vulnerabilities in the Linux kernel. This update provides the corresponding fixes for the redhat cluster suite kernel sources. A flaw was discovered in the cluster manager. A remote attacker could connect to the DLM port and block further DLM operations.

Ubuntu: Linux kernel vulnerabilities USN-489-1

Ubuntu: Linux kernel vulnerabilities USN-489-1

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A flaw was discovered in dvb ULE decapsulation. A remote attacker could send a specially crafted message and cause a denial of service. The compat_sys_mount function allowed local users to cause a denial of service when mounting a smbfs filesystem in compatibility mode.

Ubuntu: mod_perl vulnerability

Ubuntu: mod_perl vulnerability

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Alex Solovey discovered that mod_perl did not correctly validate certain regular expression matches. A remote attacker could send a specially crafted request to a web application using mod_perl, causing the web server to monopolize CPU resources. This could lead to a remote denial of service.
