02 Description

CNA: redhat

Libtiff: libtiff: arbitrary code execution or denial of service via signed integer overflow in tiff file processing

03 Exploitation and scoring

SRC: CISA, FIRST, NVD, RED HAT

Exploitation

Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.

SSVC decision

ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.

CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.

EPSS probability

0.55% probability of exploitation activity in the next 30 days.

EPSS percentile

Ranks above 44.0% of scored records. A rank, not a probability.

NVD base score

7.8 (CVSS v3.x), scored by the NVD independently of the CNA.
