It's main purpose is to serve as Webserver scripting language for dynamic HTML page programming. Besides this it could also serve as a standalone Unix filter. Fumitoshi Ukai and Denis Barbier have found several potential buffer overflows, which could lead to local privilege escalation if installed setuid (note: it's not installed setuid per default) or to remote compromise. There is currently no efficient measure against the security problems in the eperl perl interpreter other than not using or updating it. SuSE provides update packages for the defective software. SuSE Linux version before 6.3 don't include the eperl package. Download the update package from locations described below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/d2/eperl-2.2.14-206.i386.rpm e613b06d47dcfb7bbcea8c3d0c0e678b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/eperl-2.2.14-206.src.rpm c58a95f3b8ae757ea4d72f3157e2ea62 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/d1/eperl-2.2.14-203.i386.rpm e66520cc0062e25495941542dd5b1f82 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/eperl-2.2.14-203.src.rpm 34d6682524154c9fb7b5fbec4f4ea82e SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/d1/eperl-2.2.14-203.i386.rpm 4b6a5a89899320a8eeb35c149ae111f5 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/eperl-2.2.14-203.src.rpm 062b14716e52f2649f4380a6a6e4e7f9 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/d1/eperl-2.2.14-202.i386.rpm ba75d7f4a64329a3b5c324b3f0742575 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/eperl-2.2.14-202.src.rpm c7ae001d4668ba3a0524f94429b1e4e6 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/d2/eperl-2.2.14-193.sparc.rpm 9752f8b9df6ac1ffdc68cb4b552d6491 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/eperl-2.2.14-193.src.rpm f09a1ce9288c201ae63e193914fc84ce SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/d1/eperl-2.2.14-191.sparc.rpm 900eddc134215569fc88d11ce14c11f3 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/eperl-2.2.14-191.src.rpm 76aaa0efa8ae1c84b80201f73462fc26 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/d1/eperl-2.2.14-195.alpha.rpm d7b4be8d988f8cd501a33f9d2fb12a07 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/eperl-2.2.14-195.src.rpm b0379287f9078fcd244cc720fad92c4d SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/d1/eperl-2.2.14-195.alpha.rpm 78241206bc1b3927effdb5b1aa4d0ed5 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/eperl-2.2.14-195.src.rpm 325a04ec8c5c3da6b9c2fdf4e2c6c901 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/d1/eperl-2.2.14-194.alpha.rpm 88a09004e5c0c2e6174785207e111318 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/eperl-2.2.14-194.src.rpm a04cfa3e64aac49f6c148992e9a50189 PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/d2/eperl-2.2.14-178.ppc.rpm 3e05c702aca97db476155054d113ff95 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/eperl-2.2.14-178.src.rpm 67849b0c1c053eca482508fe2eac3042 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/d1/eperl-2.2.14-177.ppc.rpm 35584e2f1bcebced98fad2ae241824da source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/eperl-2.2.14-177.src.rpm 98046dce35c4adfba57cc54c018376d7 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/d1/eperl-2.2.14-176.ppc.rpm 9c36bad7ec2e8f6c31307729c7d21bc8 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/eperl-2.2.14-176.src.rpm eeaf1144dd659fe13b6a943bf40bf65b S/390 Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/s390/update/7.0/d1/eperl-2.2.14-182.s390.rpm 416974a30c9c9e435e028f2807e15a51 source rpm: ftp://ftp.suse.com/pub/suse/s390/update/7.0/zq1/eperl-2.2.14-182.src.rpm b14c7d9cbb969cda54b0d9f599f1b5cc ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - We are in the process of preparing update packages for the man package which has been found vulnerable to a commandline format string bug. The man command is installed suid man on SuSE systems. When exploited, the bug can be used to install a different man binary to introduce a trojan into the system. As an interim workaround, we recommend to `chmod -s /usr/bin/manī and ignore the warnings and errors when viewing manpages. - The file browser MidnightCommander (mc) is vulnerable to unwanted program execution. Updates are currently being built. - Two bugs were found in the text editor vim. These bugs are currently being fixed. - A bufferoverflow in sudo was discovered and fixed RPMs will be available as soon as possible. A exploit was not made public until now. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SuSE security discussion.
