Title: file: Denial of Service (GLSA 201412-48)
Exploitable: local, remote
Date: December 27, 2014
A vulnerability in file could allow a context-dependent attack to
create a Denial of Service condition.
The file utility attempts to identify a file’s format by scanning
binary data for patterns.
Vulnerable: < 5.21
Unaffected: >= 5.21
Architectures: All supported architectures
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"
