Markus Wuethrich discovered that sudo did not always verify the user when a group was specified in the Runas_Spec. A local attacker could exploit this to execute arbitrary code as root if sudo was configured to allow the attacker to use a program as a group when the attacker was not a part of that group.

Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory manager did not properly handle when applications grow stacks into adjacent memory regions. A local attacker could exploit this to gain control of certain applications, potentially leading to privilege escalation, as demonstrated in attacks against the X server. (CVE-2010-2240) [More...]

Ubuntu 973-1: KOffice vulnerabilities

Ubuntu 973-1: KOffice vulnerabilities

Will Dormann, Alin Rad Pop, Braden Thomas, and Drew Yao discovered that the Xpdf used in KOffice contained multiple security issues in its JBIG2 decoder. If a user or automated system were tricked into opening a crafted PDF file, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program. (CVE-2009-0146, [More...]

Ubuntu 972-1: FreeType vulnerabilities

Ubuntu 972-1: FreeType vulnerabilities

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