CVE-2016-1628

CVE-2016-1628 describes an out-of-bounds read vulnerability in OpenJPEG, specifically within the pi.c file, as used in PDFium in Google Chrome prior to version 48.0.2564.109. This flaw allows remote attackers to execute arbitrary code or cause a denial of service by crafting a malicious JPEG 2000 image embedded in a PDF document. The vulnerability stems from a lack of precision value validation in functions like opj_pi_next_rpcl, opj_pi_next_pcrl, and opj_pi_next_cprl. With a CVSS v3 score of 6.3 (Medium), this vulnerability has a low attack complexity and requires user interaction (UI:R) to exploit, but can be triggered remotely (AV:N). Successful exploitation could lead to limited impact on confidentiality, integrity, and availability (C:L/I:L/A:L). There is no evidence of active exploitation in the wild, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, with only one mention and one article identified, indicating low public attention.
