CVE-2026-57456 Vim: Arbitrary Code Execution via Python Omni-Completion Docstrings

Vim is an open source, command line text editor. Prior to 9.2.0699, Vim's Python omni-completion runtime/autoload/python3complete.vim and the legacy pythoncomplete.vim executes reconstructed function and class definitions from the current buffer with exec as part of populating the completion...

CVE-2026-57456

Vim (prior to 9.2.0699) is vulnerable in its Python omni-completion: during reconstruction of function/class definitions, docstrings are inlined between triple quotes without escaping, allowing a hostile buffer to break out of the literal and execute attacker-controlled Python during omni-complet...

jq: jq: Arbitrary Code Execution or Denial of Service via Signed Integer Overflow

A flaw was found in jq, a tool used for processing JSON data from the command line. A remote attacker can exploit a vulnerability by providing a specially crafted large number as input. This can cause an internal calculation error, leading to a memory overflow where the attacker can write their o...

postgresql: PostgreSQL libpq: Buffer overflow allows server superuser to overwrite client stack memory

A flaw was found in PostgreSQL libpq. A server superuser can exploit a buffer overflow vulnerability in the PQfn function, which is used by client functions such as loexport, loread, lolseek64, and lotell64. This allows the superuser to send an arbitrarily large response, overwriting the client's...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...
