Bug#643967: prelink -u fails on some binaries; this breaks debsums
severity 643967 important tag 643967 -security thanks This problem should not be considered a security issue. Anyone utilizing prelink should be aware of the fact that it changes binaries, and there is the possibility that those changes aren't reversible; leading to differing checksums in tools like debsums. The appropriate course of action for one so concerned is to completely avoid prelink until it is 100% reliably reversible.

Bug#643967: prelink -u fails on some binaries; this breaks debsums
Package: prelink Version: 0.0.20090925-1 Severity: serious On i386, consider the following series of commands: # dpkg -i psmisc_22.14-1_i386.deb (snipped) # /usr/sbin/prelink -y --md5 /usr/bin/pstree bb296a950a089ec8a837a1c97b47eeb9 /usr/bin/pstree # /usr/sbin/prelink -mR -T /usr/bin/pstree # /usr/sbin/prelink -y --md5 /usr/bin/pstree prelink: Could not write temporary for /usr/bin/pstree: Layout error: overlapping sections The problem also happens with: 5d81333c2cf40ddee6d18139b01afd4b /usr/bin/peekfd prelink: Could not write temporary for /usr/bin/peekfd: Layout error: overlapping sections 95ae7ca0bc1685de6f840469efee /usr/bin/killall prelink: Could not write temporary for /usr/bin/killall: Layout error: overlapping sections ffc1b9a380a7afb6fdf32f9cd5b3c7d0 /bin/fuser prelink: Could not write temporary for /bin/fuser: Layout error: overlapping sections The same error crops uo when attempting any sort of "undo" operation. This breaks debsums runs, which is a pretty serious security problem. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
