A vulnerability in file could allow a context-dependent attack to create a Denial of Service condition.
|Package||sys-apps/file on all architectures|
|Affected versions||< 5.21|
|Unaffected versions||>= 5.21|
The file utility attempts to identify a file’s format by scanning binary data for patterns.
An issue with the ELF parser used by the file utility can cause a resource consumption when reading a specially-crafted ELF binary.
A context-dependent attacker may be able to cause Denial of Service.
There is no known workaround at this time.
All file users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/file-5.21"
