Package: tripwire
Version: 2.4.2.2-5+b1
Severity: important
Dear Maintainer,
Tripwire segfaults on 32 bit 686-pae kernels. First, after an update,
I started investigating and came across this:
# strace tripwire
execve("/usr/sbin/tripwire", ["tripwire"], [/* 18 vars */]) = 0
uname({sysname="Linux", nodename="stat.fsu.edu", ...}) = 0
brk(0) = 0x993b000
brk(0x993bd80) = 0x993bd80
set_thread_area({entry_number:-1, base_addr:0x993b880, limit:1048575,
seg_32bit:1, contents:0, read_exec_only:0, limit_in_pages:1, seg_not_present:0,
useable:1}) = 0 (entry_number:6)
readlink("/proc/self/exe", "/usr/sbin/tripwire", 4096) = 18
brk(0x995cd80) = 0x995cd80
brk(0x995d000) = 0x995d000
access("/etc/ld.so.nohwcap", F_OK) = 0
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0} ---
+++ killed by SIGSEGV +++
Segmentation fault
So on one machine I purged the package after backing up my policy
files and got this:
Generating site key (this may take several minutes)...
/var/lib/dpkg/info/tripwire.postinst: line 108: 32578 Broken pipe (
echo "$site_pass"; sleep 2; echo "$site_pass" )
32579 Segmentation fault | $twadmin -m G -S "$SITEKEYFILE" > /dev/null 2>&1
Doing an strace on twadmin gives this
# strace /usr/sbin/twadmin
execve("/usr/sbin/twadmin", ["/usr/sbin/twadmin"], [/* 17 vars */]) = 0
uname({sysname="Linux", nodename="spline", ...}) = 0

Today's update works perfectly on the amd64 arch. Thanks.
