ViewVC before 1.1.11 allows remote attackers to bypass the cvsdb rowlimit configuration setting, and consequently conduct resource-consumption attacks, via the limit parameter, as demonstrated by a "query revision history" request.

Cross-site scripting (XSS) vulnerability in viewvc.py in ViewVC 1.0 before 1.0.9 and 1.1 before 1.1.2 allows remote attackers to inject arbitrary web script or HTML via the view parameter. NOTE: some of these details are obtained from third party information.

Unspecified vulnerability in ViewVC 1.0 before 1.0.9 and 1.1 before 1.1.2 has unknown impact and remote attack vectors related to "printing illegal parameter names and values."

Cross-site scripting (XSS) vulnerability in the "extra" details in the DiffSource.getrow function in lib/viewvc.py in ViewVC 1.0.x before 1.0.13 and 1.1.x before 1.1.16 allows remote authenticated users with repository commit access to inject arbitrary web script or HTML via the "function name" line.
