CVE-2024-7006: Libtiff: null pointer dereference in tif_dirinfo.c

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 1.5% (FIRST EPSS); higher than 74.3% 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. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Azure Linux 3.0 ARM 4.6.0-4; Azure Linux 3.0 x64 4.6.0-4; CBL Mariner 2.0 ARM 4.6.0-3.

Low priority for now. Upgrade to Azure Linux 3.0 ARM 4.6.0-4; Azure Linux 3.0 x64 4.6.0-4; CBL Mariner 2.0 ARM 4.6.0-3 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service.
