Ubuntu 4.10 / 5.04 / 5.10 : netpbm-free vulnerability (USN-210-1)

A buffer overflow was found in the 'pnmtopng' conversion program. By tricking an user or automated system to process a specially crafted PNM image with pnmtopng, this could be exploited to execute arbitrary code with the privileges of the user running pnmtopng. Note that Tenable Network Security...

Ubuntu 4.10 / 5.04 : binutils regression (USN-136-2)

It was discovered that the packages from USN-136-1 had a flawed patch with regressions that caused the ld linker to fail. The updated packages fix this. We apologize for the inconvenience. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu...

Ubuntu 4.10 / 5.04 : squid vulnerability (USN-129-1)

It was discovered that Squid did not verify the validity of DNS server responses. When Squid is started, it opens a DNS client UDP port whose number is randomly assigned by the operating system. Unless your network firewall is configured to accept DNS responses only from known good nameservers,...

Ubuntu 4.10 / 5.04 : vim vulnerability (USN-154-1)

Georgi Guninski discovered that it was possible to construct Vim modelines that execute arbitrary shell commands by wrapping them in glob or expand function calls.

Ubuntu 4.10 / 5.04 : php4 vulnerability (USN-207-1)

A bug has been found in the handling of the openbasedir directive handling. Contrary to the specification, the value of openbasedir was handled as a prefix instead of a proper directory name even if it was terminated by a slash '/'. For example, this allowed PHP scripts to access the directory...

Ubuntu 4.10 : cyrus21-imapd vulnerability (USN-87-1)

Sean Larsson discovered a buffer overflow in the IMAP 'annotate' extension. This possibly allowed an authenticated IMAP client to execute arbitrary code with the privileges of the Cyrus IMAP server. Note that Tenable Network Security has extracted the preceding description block directly from the...

Ubuntu 4.10 / 5.04 : php4, php4-universe fixed packages (USN-147-2)

USN-147-1 1 fixed a remote code execution vulnerability in the XMLRPC module of the PEAR library. Unfortunately the packages announced in USN-147-1 were faulty and shipped broken xmlrpc modules. The updated packages ship correct modules. We apologize for the inconvenience. 1...

Ubuntu 4.10 : php4 vulnerabilities (USN-99-2)

USN-99-1 fixed a safe mode bypass which allowed malicious PHP scripts to circumvent path restrictions by creating a specially crafted directory whose length exceeded the capacity of the realpath function CAN-2004-1064. However, this caused severe regressions, some applications like SquirrelMail a...

Ubuntu 4.10 / 5.04 : apache vulnerability (USN-160-2)

USN-160-1 fixed two vulnerabilities in the Apache 2 server. The old Apache 1 server was also vulnerable to one of the vulnerabilities CAN-2005-2088.
