Package: procps
Version: 1:3.2.7-3
Severity: normal
When running "sysctl net.ipv6.conf", sysctl crashes after printing most
(or all?) output, printing the following to stderr:
*** glibc detected *** free(): invalid next size (fast): 0x0000000000503030 ***
Aborted
I have reproduced the problem on multiple amd64 machines running debian,
and one running ubuntu. I have not been able to reproduce it on i386.
According to Steinar Gunderson <[EMAIL PROTECTED]> (who I asked to
reproduce the problem), the following patch should do the trick:
--- procps-3.2.7.orig/sysctl.c
+++ procps-3.2.7/sysctl.c

- tmpname = malloc(strlen(name)+strlen(PROC_PATH)+1);
+ tmpname = malloc(strlen(name)+strlen(PROC_PATH)+2);
strcpy(tmpname, PROC_PATH);
strcat(tmpname, name);
slashdot(tmpname+strlen(PROC_PATH),'.','/'); /* change . to / */
The reason why the extra byte is necessary can (again according to
Steinar) be spotted in sysctl.c:196.
