CVE-2012-2841

CVE-2012-2841 describes an integer underflow vulnerability in the exif_entry_get_value function within the libexif library (version 0.6.20). This flaw could allow remote attackers to execute arbitrary code by manipulating a crafted buffer-size parameter during EXIF tag formatting, leading to a heap-based buffer overflow. The vulnerability carries a CVSS score of 7.5, indicating high severity with network-based attacks, low complexity, and potential for partial compromise of confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
