Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
gio/gsocks4aproxy.c in GNOME GLib before 2.82.1 has an off-by-one error and resultant buffer overflow because SOCKS4_CONN_MSG_LEN is not sufficient for a trailing '\0' character.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-120

A fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

Fixed in 2.82.1
Recommended fix High confidence

GLib 2.82.1 or later

  1. Upgrade GNOME GLib to version 2.82.1 or later to address the off-by-one buffer overflow in gio/gsocks4aproxy.c
  2. Verify the installed GLib version after upgrade: `glib-config --version` or `pkg-config --modversion glib-2.0`
  3. For Debian 11.0 systems, apply Debian security updates or upgrade GLib packages: `apt update && apt install libglib2.0-0`
  4. For NetApp Active IQ Unified Manager and Ontap Tools, refer to NetApp security advisories for specific patch instructions
