Created attachment 956421 [details] Proposed patch Hi Jeff, Hi Patsy, I have uploaded a specially crafted patch that combines both of the fixes for PR 17552, built against the RHEL 7.1 sources. I hope that this helps. Cheers Nick
Thanks Nick. I'm watching this very closely as we have a small window where we can fix this for RHEL 7.1. However, right now, this stuff is not slated for 7.1 by nature of no RHEL BZs from the security team, which is probably an artifact of these being marked as med/med or lower from an security standpoint. My preference is to fix this and the controlled write in the BFD ELF code for RHEL 7.1 and RHEL 6.7. I do _not_ want to issue z-streams for these issues if we can avoid it.

Created attachment 1083729 [details] Remove resource leak from binutils-th1162655.patch Note - the patch for this BZ inadvertently introduced a resource leak into the binutils sources. This leak is detected by the covscan tool. What can happen is that a buffer of 8192 bytes is allocated but not freed. This only happens when an illegal archive is being processed, and in this case the program will exit very shortly afterwards. So the resource will not prevent the proper functioning of the program on valid archives, and it will not prevent the program from reporting and exiting (cleanly) on invalid archives. Since this problem has been detected so late in the 7.2 release process, a fix for it is being delayed until 7.3. The update to fix the patch is uploaded here. Cheers Nick
Makes sense to me.
