The unaffected packages listed in GLSA 201409-09 had an incomplete fix. Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Bash is the standard GNU Bourne Again SHell. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-shells/bash < 4.2_p48-r1 *>=3D 3.1_p18-r1 *>=3D 3.2_p52-r1 *>=3D 4.0_p39-r1 *>=3D 4.1_p12-r1 >=3D 4.2_p48-r1 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Stephane Chazelas reported that Bash incorrectly handles function definitions, allowing attackers to inject arbitrary code (CVE-2014-6271). Gentoo Linux informed about this issue in GLSA 201409-09. Tavis Ormandy reported that the patch for CVE-2014-6271 was incomplete. As such, this GLSA supersedes GLSA 201409-09. Impact =3D=3D=3D=3D=3D=3D A remote attacker could exploit this vulnerability to execute arbitrary commands even in restricted environments. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time.
