[Pkg-openssl-devel] Bug#1131904: libssl3t64: "LS alert, bad record mac (532)" / "decryption failed or bad record mac" since 3.6.1 on ppc64

[Philipp Klaus Krause]

Package: libssl3t64
Version: 3.6.0-2
Severity: normal
X-Debbugs-Cc: debian-powerpc at lists.debian.org, pkk at spth.de
User: debian-powerpc at lists.debian.org
Usertags: ppc64

Dear Maintainer,

about a week ago, I upgraded libssl3t64 on my ppc64 system to 3.6.1-3. This resulted in failures (see below). After downgrading to 3.6.0-2, the failures disappeared. An amd64 system on the same network was not affected (there 3.6.1 works).

Failure example:
