Our readers told us about several vulnerabilities that caught the public's eye this weekend. Here's a brief summary:
OpenSSH patched two vulnerabilities in the release of OpenSSH 4.4. (Thanks for letting us know, Hamid.)
One denial-of-service condition was discovered by Tavis Ormandy, and could cause the SSH daemon "to spin until the login grace time expired." This issue affects OpenSSH if it has support for SSH version 1 enabled. (Please migrate to SSH version 2, if you can do so and haven't already.) A proof-of-concept exploit for this vulnerability is floating around. The CVE reference for this vulnerability is CVE-2006-4924.
The other denial-of-service condition was discovered by Mark Dowd. It could, theoretically, lead to remote execution of arbitrary code. This is probably the strongest reason to upgrade to OpenSSH 4.4 sooner, rather than later, although the release also includes some enticing new functionality.
An XSRF/CSRF vulnerability was reported in phpMyAdmin, a web-based front-end for managing MySQL servers. The bug could allow an attacker "to inject arbitrary SQL commands by forcing an authenticated user to follow a crafted link." The issue was fixed in the first release candidate for phpMyAdmin 2.9.1.
