Denial of service (DoS) when processing Git credentials
Impact
A denial of services (DoS) vulnerability was discovered in Wrangler Git package affecting versions up to and including v1.0.0.
Specially crafted Git credentials can result in a denial of service (DoS) attack on an application that uses Wrangler due to the exhaustion of the available memory and CPU resources. This is caused by a lack of input validation of Git credentials before they are used, which may lead to a denial of service in some cases. This issue can be triggered when accessing both private and public Git repositories.
Workarounds
A workaround is to sanitize input passed to the Git package to remove potential unsafe and ambiguous characters. Otherwise, the best course of action is to update to a patched Wrangler version.
Patches
Patched versions include v1.0.1 and later and the backported tags - v0.7.4-security1, v0.8.5-security1 and v0.8.11.
