Gentoo Linux Security Advisory

Title: file: Denial of Service (GLSA 201412-48)
Severity: normal
Exploitable: local, remote
Date: December 27, 2014
Bug(s): #532686
ID: 201412-48


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.

Affected Packages

Package: sys-apps/file
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"
