HEADS UP: breakage with linux emulation + SA-11:05.unix
Hi all, It appears that the security fix in SA-11:05.unix exposed a bug in the linux emulation code: Linux has a different size of sockaddr_un than FreeBSD, and the linux emulation code was passing socket addresses through without doing any translation first. This appears to break all X-using Linux code -- both applications and plugins such as the widely-used flash plugin -- and probably other Linux applications too. I am working on a fix for this and will send an updated advisory out as soon as it's ready. -- Colin Percival Security Officer, FreeBSD | freebsd.org | The power to serve Founder / author, Tarsnap | tarsnap.com | Online backups for the truly paranoid
