CVE-2025-3360: Glibc: glib prior to 2.82.5 is vulnerable to integer overflow and buffer under-read when parsing a very long invalid iso 8601 timestamp with g_date_time_new_f

Noroxi assessment

Priority: Monitor (action score 14/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.64% (FIRST EPSS); higher than 50.8% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: gitlab.gnome.org/GNOME/glib glib 2.82.5; azl3 glib 2.78.6-2 on Azure Linux 3.0 2.78.6-2; cbl2 glib 2.71.0-5 on CBL Mariner 2.0 2.71.0-5.

Low priority for now. Upgrade to gitlab.gnome.org/GNOME/glib glib 2.82.5; azl3 glib 2.78.6-2 on Azure Linux 3.0 2.78.6-2; cbl2 glib 2.71.0-5 on CBL Mariner 2.0 2.71.0-5 or later.
