Description Michael Orlitzky gentoo-dev 2017-11-28 19:57:54 UTC
From the 1.1.3 ChangeLog,

Security Fix for CVE-2017-15914: Incorrect implementation of access controls allows remote users to override repository restrictions in Borg servers. A user able to access a remote Borg SSH server is able to circumvent access controls post-authentication. Affected releases: 1.1.0, 1.1.1, 1.1.2. Releases 1.0.x are NOT affected.

The fixed version is already in the tree but will need an amd64 stabilization.

Sorry for the delay, Anthony.  

Downgrading to B3.  Ambiguous "access control" details from upstream and no PoC for ACE/RCE.

Tree is clean.
