| Assigned: | 2006-01-09 | ||||||||
| Published: | 2006-01-09 | ||||||||
| Updated: | 2018-10-19 | ||||||||
| Summary: | The kernfs_xread function in kernfs in NetBSD 1.6 through 2.1, and OpenBSD 3.8, does not properly validate file offsets against negative 32-bit values that occur as a result of truncation, which allows local users to read arbitrary kernel memory and gain privileges via the lseek system call. | ||||||||
