Background ========= ViewCVS is a browser interface for viewing CVS and Subversion version control repositories through a web browser. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apps/viewcvs = 0.9.2_p20041207-r1 Description ========== The tar export functions in ViewCVS bypass the 'hide_cvsroot' and 'forbidden' settings and therefore expose information that should be kept secret (CAN-2004-0915). Furthermore, some error messages in ViewCVS do not filter user-provided information, making it vulnerable to a cross-site scripting attack (CAN-2004-1062). Impact ===== By using the tar export functions, a remote attacker could access information that is configured as restricted. Through the use of a malicious request, an attacker could also inject and execute malicious script code, potentially compromising another user's browser. Workaround ========= There is no known workaround at this time. Resolution ========= All ViewCVS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot--verbose "> =www-apps/viewcvs-0.9.2_p20041207-r1" References ========= [ 1 ] CAN-2004-0915 https://www.cve.org/CVERecord?id=CVE-CAN-2004-0915 [ 2 ] CAN-2004-1062 https://www.cve.org/CVERecord?id=CVE-CAN-2004-1062 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200412-26 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to
Hajvan Sehic discovered several vulnerabilities in viewcvs, a utility for viewing CVS and Subversion repositories via HTTP. When exporting a repository as a tar archive the hide_cvsroot and forbidden settings were not honoured enough.. --------------------------------------------------------------------------Debian Security Advisory DSA 605-1
