Slackware Security Advisory: glibc 2.1.3 vulnerabilities patchedSep 06, 2000, 19:26 (0 Talkback[s])(Other stories by Nick C. Doyle) Date: Wed, 6 Sep 2000 07:02:35 -0300 Three locale-related vulnerabilities with glibc 2.1.3 were recently reported on BugTraq. These vulnerabilities could allow local users to gain root access. Users of Slackware 7.0, 7.1, and -current are strongly urged to upgrade to the new glibc packages in the -current branch. glibc 2.1.3 AVAILABLE - (a1/glibcso.tgz, d1/glibc.tgz, des1/descrypt.tgz) The three locale-related vulnerabilities with glibc-2.1.3 have been patched using the CVS glibc patches provided by Solar Designer. PACKAGE INFORMATION: a1/glibcso.tgz: This package contains the runtime libraries for glibc 2.1.3. All users of Slackware 7.0 through -current should upgrade this package. d1/glibc.tgz: This is the full glibc 2.1.3 package, complete with headers and static libraries. If you had previously installed this package, you need to upgrade it. des1/descrypt.tgz: Contains a DES-enabled libcrypt.so library. If you have this package, you need to upgrade it as well. IMPORTANT: Be sure to upgrade this package *AFTER* glibcso.tgz and glibc.tgz. WHERE TO FIND THE NEW PACKAGES: All new packages can be found in the -current branch:
