Hi, Maurice van der Pot of Gentoo reported a bug in ssmtp 2.62: The from_format() function in ssmtp.c will call strdup() on an unitialized memory if the user's gecos is unset and "FromLineOverride" is disabled in the configuration. This might disclose memory contents by sending them off in the the "From:" field of an email or cause a (client) crash. We're handling this as bug 234391 [ https://bugs.gentoo.org/234391 ]. Patch: https://bugs.gentoo.org/attachment.cgi?id=165005 ssmtp 2.61 is not affected.
As Tomas Hoger pointed out on IRC, 2.61 is affected as well -- I accidently checked our patched sources and not the vanilla tarball. We added a patch to 2.61 in 2006, and accidently dropped it when bumping to 2.62. Back then, this was bug 127592 [ https://bugs.gentoo.org/127592 ]. Thanks, Robert
