Name of the Vulnerable Software and Affected Versions NSF Unidata NetCDF-C (affected versions not specified)

Description A flaw exists in the parsing of variable names, stemming from insufficient validation of user-supplied data length before copying it into a fixed-length stack-based buffer. This can allow a remote attacker to execute arbitrary code in the context of the current user. User interaction is required, such as visiting a malicious page or opening a malicious file, to trigger the issue.
