2011-02-19 CVE-2011-0724 Cryptographic Issues vulnerability in Ubuntu Edubuntu and Live DVD
The Live DVD for Edubuntu 9.10, 10.04 LTS, and 10.10 does not correctly regenerate iTALC private keys after installation, which causes each installation to have the same fixed key, which allows remote attackers to gain privileges.

2010-08-10 CVE-2010-0834 Improper Authentication vulnerability in Ubuntu Linux 10.04/9.10
The base-files package before 5.0.0ubuntu7.1 on Ubuntu 9.10 and before 5.0.0ubuntu20.10.04.2 on Ubuntu 10.04 LTS, as shipped on Dell Latitude 2110 netbooks, does not require authentication for package installation, which allows remote archive servers and man-in-the-middle attackers to execute arbitrary code via a crafted package.

2009-01-02 CVE-2006-7236 Configuration vulnerability in Invisible-Island Xterm NIL
The default configuration of xterm on Debian GNU/Linux sid and possibly Ubuntu enables the allowWindowOps resource, which allows user-assisted attackers to execute arbitrary code or have unspecified other impact via escape sequences.

2005-12-31 CVE-2005-3625 Resource Management Errors vulnerability in multiple products
Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

2005-03-01 CVE-2004-0989 Remote Stack Buffer Overflow vulnerability in Libxml2
Multiple buffer overflows in libXML 2.6.12 and 2.6.13 (libxml2), and possibly other versions, may allow remote attackers to execute arbitrary code via (1) a long FTP URL that is not properly handled by the xmlNanoFTPScanURL function, (2) a long proxy URL containing FTP data that is not properly handled by the xmlNanoFTPScanProxy function, and other overflows related to manipulation of DNS length values, including (3) xmlNanoFTPConnect, (4) xmlNanoHTTPConnectHost, and (5) xmlNanoHTTPConnectHost.
