Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
A flaw in the Ruby standard library might allow remote attackers to
cause a Denial of Service attack.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Ruby is an interpreted object-oriented programming language. The
elaborate standard library includes the "BigDecimal" class.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/ruby < 1.8.6_p369 >=3D 1.8.6_p369
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Tadayoshi Funaba reported that BigDecimal in
ext/bigdecimal/bigdecimal.c does not properly handle string arguments
containing overly long numbers.
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker could exploit this issue to remotely cause a Denial
of Service attack.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All Ruby users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Ddev-lang/ruby-1.8.6_p369"
