EPSS: 4.1% probability of exploitation in the next 30 days

Published: 2012-08-13 · updated 2026-06-16
Weakness: CWE-119

Description

The t2p_read_tiff_init function in tiff2pdf (tools/tiff2pdf.c) in LibTIFF 4.0.2 and earlier does not properly initialize the T2P context struct pointer in certain error conditions, which allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers a heap-based buffer overflow.

Affected products

libtiff: through 4.0.2; 3.4, 3.4-beta18, 3.4-beta24, 3.4-beta28, 3.4-beta29, 3.4-beta31 (+50)
