CVE-2016-9448: The TIFFFetchNormalTag function in LibTiff 4.0.6 allows remote attackers to cause a denial of service (NULL pointer dereference and crash)…

HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 4.9% (FIRST EPSS); higher than 92.3% 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.
  • Fixed version: tiff (Alpine:v3.2) 4.0.7-r0; tiff (SUSE:Linux Enterprise Desktop 12 SP1) 4.0.7-35.1.

Low priority for now. Upgrade to tiff (Alpine:v3.2) 4.0.7-r0; tiff (SUSE:Linux Enterprise Desktop 12 SP1) 4.0.7-35.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The TIFFFetchNormalTag function in LibTiff 4.0.6 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by setting the tags TIFF_SETGET_C16ASCII or TIFF_SETGET_C32_ASCII to values that access 0-byte arrays. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9297.
