[slackware-security] rpath security issues (SSA:2024-275-03)

Several packages have been updated for Slackware 15.0 and -current to fix
rpath security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
Several ELF objects were found to have rpaths pointing into /tmp, a world
writable directory. This could have allowed a local attacker to launch denial
of service attacks or execute arbitrary code when the affected binaries are
run by placing crafted ELF objects in the /tmp rpath location. All rpaths with
an embedded /tmp path have been scrubbed from the binaries, and makepkg has
gained a lint feature to detect these so that they won't creep back in.
extra/llvm-17.0.6-i586-2_slack15.0.txz: Rebuilt.
Remove rpaths from binaries.
(* Security fix *)
patches/packages/cryfs-0.10.3-i586-5_slack15.0.txz: Rebuilt.
Remove rpaths from binaries.
(* Security fix *)
patches/packages/espeak-ng-1.50-i586-4_slack15.0.txz: Rebuilt.
Remove rpaths from binaries.
(* Security fix *)
patches/packages/libvncserver-0.9.13-i586-4_slack15.0.txz: Rebuilt.

patches/packages/marisa-0.2.6-i586-5_slack15.0.txz: Rebuilt.

(* Security fix *)
patches/packages/pkgtools-15.0-noarch-44_slack15.0.txz: Rebuilt.
makepkg: when looking for ELF objects with --remove-rpaths or
--remove-tmp-rpaths, avoid false hits on files containing 'ELF' as part
of the directory or filename.
Also warn about /tmp rpaths after the package is built.
patches/packages/spirv-llvm-translator-13.0.0-i586-2_slack15.0.txz: Rebuilt.
Remove rpaths from binaries.
(* Security fix *)
testing/packages/llvm-18.1.8-i686-2_slack15.0.txz: Rebuilt.
