Stracener> The pkg* programs pkgtrans, pkginfo, pkgcat, pkginstall, and pkgparam can be used to mount etc/shadow printing attacks as a result of the "dacread" permission (cf. /etc/security/tcb/privs). The procedural differences between the individual exploits for each of these utilities are therefore inconsequential. CVE-1999-0988 should be merged with CVE-1999-0828. From the standpoint of maintaining consistency of the level of abstraction used in CVE, the co-existence of CANS 1999-0988/1999-0828 present two choices: either merge 0988 with 0828, or split 0828 into 4 distinct candidates, keeping 0988 intact. Due to the very small differences (in principle) between the exploits subsumed by 0828 and 0988 and the shared dacread permissions of the pkg* suite, I suggest a merge. Below is a summary of the data upon which my decision was based. utility exploit -------- ---------------------------------- pkgtrans --> symlink + dacread permission prob pkginfo --> truss (debugging utility) in conjunction with pkginfio -d etc/shadow. In this case, it captures the interaction between pkginfo the shadow file. Once again: dacread. pkgcat --> buffer overflow + dacread permission prob pkginstall -> buffer overflow + dacread permission prob pkgparam --> -f etc/shadow (works because of dacread). Christey> This is a tough one. While there are few procedural differences, one could view "assignment of an improper permission" as a "class" of problems along the lines of buffer overflows and the like. Just like some programs were fine until they got turned into CGI scripts, this could be an emerging pattern which should be given consideration. Consider the Eyedog and scriptlet.typelib ActiveX utilities being marked as safe for scripting (CVE-1999-0668 and 0669). ftp://ftp.sco.com/SSE/security_bulletins/SB-99.28a loosely alludes to this problem; the README for patch SSE053 effectively confirms it.
