Hello Jonas Meurer,I reported a bug with the recent (Sept. 10) libarchive12 security update (Debian BTS 838243) and heard back from Andreas Henriksson that I should reach out to the package uploader and Debian LTS team directly.
I appreciate the great work that you and the LTS team are doing to keep wheezy secure. The issue seems fairly minor and is described in the bug tracker, https://bugs.debian.org/838243. Thanks!
Regards, Bruce Toll
