Title:
Illegal opcode in libssl
Status in openssh package in Ubuntu:
New
Bug description:
Many programs using openssl now fail, typically with messages such as
Illegal instruction (core dumped)
This seems to be a serious error, since it affects, for example,
update-manager. Since this makes it harder to get security updates, I
would also consider it a security vulnerability.
The issue seems to be that openssl seems to be an attempt to use an
illegal opcode. A few sample entries in /var/log/syslog are:
