CVE-2026-121942

A flaw was found in zbar. An attacker could exploit this vulnerability by enticing a user to process a specially crafted SQ code image. During decoding, unchecked coordinates near image boundaries trigger an out-of-bounds memory read. This flaw allows an attacker to crash the application, resulti...

CVE-2026-121942

ZBar through 0.23.95 contains an out-of-bounds read vulnerability in zbarsqdecode in zbar/sqcode.c that allows attackers to read heap memory outside the image buffer via crafted SQ code images. Attackers can supply an image with a skewed SQ code finder pattern near the edge, producing unchecked...

CVE-2026-121942

The ZBar library (versions through 0.23.95 ) is vulnerable to an out-of-bounds read in the _zbar_sq_decode() function located in zbar/sqcode.c. An attacker can exploit this by providing a crafted SQ code image with a skewed finder pattern near the edge. This causes the decoder to produce unchecke...
