Name of the Vulnerable Software and Affected Versions OSGeo gdal versions prior to 3.11.0
Description A flaw exists in OSGeo gdal related to improper restriction of operations within the bounds of a memory buffer. This issue is located in the frmts/zlib/contrib/infback9 modules, specifically within the inftree9.c file. The problem stems from incorrect pointer arithmetic in the bundled zlib library, potentially allowing attackers to corrupt heap memory through malformed compressed data, which could lead to remote code execution.
Recommendations Update to version 3.11.0 or later.
