GHSA-GF82-22G8-PRC5

Vulnerability from github – Published: 2022-05-24 17:44 – Updated: 2024-04-04 03:04

Details

xbuf_format_converter, used as part of exif_read_data, was appending a terminating null character to the generated string, but was not using its standard append char function. As a result, if the buffer was full, it would result in an out-of-bounds write. This issue affects HHVM versions prior to 4.56.3, all versions between 4.57.0 and 4.80.1, all versions between 4.81.0 and 4.93.1, and versions 4.94.0, 4.95.0, 4.96.0, 4.97.0, 4.98.0.

Severity ?

9.8 (Critical)
