Yes. Known bug. See the following patch from Eric Allman.

Subject: patch to sendmail 8.7.6
Date: 21 Sep 1996 19:01:28 -0700
Message-ID: <5226lo$70k@knecht.Oxford.Reference.COM>

The following patches fix small bugs in 8.7.6. I do not plan to do an
8.7.7 release, since 8.8 is due out in just a few days. If these are
causing you problems, apply the following fixes; otherwise, hold on
until 8.8 is out.
The "&" character in Gecos fields doesn't expand the login name into
the full name properly. The easy workaround is to just use the full
name (without "&") in the Gecos field of all passwd entries. If this
is not possible, apply the following patch:
*** util.c.orig Thu Sep 19 08:08:17 1996
- --- util.c Sun Sep 22 03:26:17 1996
***************
*** 418,424 ****
{
if (*p == '&')
{
! snprintf(bp, SPACELEFT(buf, bp), "%s", login);
*bp = toupper(*bp);
bp += strlen(bp);
}
- --- 418,424 ----
{
if (*p == '&')
{
! snprintf(bp, buflen - (bp - buf), "%s", login);
*bp = toupper(*bp);
bp += strlen(bp);
}
On some architectures, a one-byte buffer overflow in get_column (used
by text map lookups) can cause core dumps. (In many cases this is not
a problem because the compiler rounds the three byte buffer up to four
bytes to get long alignment.) If this is a problem, apply the following
patch:
*** util.c.orig Sat Sep 21 18:49:45 1996
- --- util.c Sat Sep 21 18:49:59 1996
***************
*** 1865,1871 ****
char *p;
char *begin, *end;
int i;
! char delimbuf[3];
if (delim == '\0')
strcpy(delimbuf, "\n\t ");
- --- 1865,1871 ----
char *p;
char *begin, *end;
int i;
! char delimbuf[4];
if (delim == '\0')
strcpy(delimbuf, "\n\t ");
If you want to try 8.8.Beta, it is available on FTP.Sendmail.ORG in
/ucb/src/sendmail/.beta. Change into that directory and follow the
directions in the welcome message to get the latest Beta version.
