Ansible-core: ansible-core: ansible.builtin.git invokes git without a `--` separator, allowing argument injection via a `-`-leading repository url (e.g. --upload-pack) -> rce
A flaw was found in ansible-core's ansible.builtin.git module. The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as…

High 7.1
Gnutls: gnutls: authentication bypass via nul character in username
A flaw was found in gnutls. Servers configured with RSA-PSK (Rivest–Shamir–Adleman – Pre-Shared Key) wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username…

Medium 6.7
Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to a…
