Summary

libewf through 20260924 contains a heap out-of-bounds read vulnerability in libewf_lef_extended_attribute_read_data() because UTF-16 name and value sizes are validated before being doubled. Attackers can supply a crafted .L01/.Lx01 file with oversized 'ea' metadata counts to crash the application or leak uninitialized heap memory through extended attributes.

Risk Assessment

The vulnerability can lead to application crashes (denial of service) and leakage of uninitialized heap memory, potentially exposing sensitive data. The risk affects systems processing untrusted EWF disk image files.

Recommendation

Update libewf to a version newer than 20260924 if available, or avoid processing untrusted .L01/.Lx01 files. Consider validating metadata sizes before use.
