-----BEGIN PGP SIGNED MESSAGE----- A buffer overflow has been identified in all versions of the libc 5 packages shipped with Red Hat Linux. The most affected systems are those that are libc 5 based (Red Hat Linux 4.2 and older). Only Intel and Sparc architectures are affected. The Red Hat Linux 5.x releases are glibc (libc 6) based, and Red Hat does not ship any binaries linked against libc 5 that might be used for compromising the system's security. However, Red Hat Linux 5.x releases do include for backwards compatibility a package containg a vulnerable library. Users of Red Hat Linux are recommended to upgrade to the new packages available under updates directory on our ftp site: Red Hat Linux 4.2: ================== i386: rpm -Uvh ftp://updates.redhat.com/4.2/i386/libc-5.3.12-18.4.i386.rpm rpm -Uvh ftp://updates.redhat.com/4.2/i386/libc-debug-5.3.12-18.4.i386.rpm rpm -Uvh ftp://updates.redhat.com/4.2/i386/libc-devel-5.3.12-18.4.i386.rpm rpm -Uvh ftp://updates.redhat.com/4.2/i386/libc-profile-5.3.12-18.4.i386.rpm rpm -Uvh ftp://updates.redhat.com/4.2/i386/libc-static-5.3.12-18.4.i386.rpm sparc: rpm -Uvh ftp://updates.redhat.com/4.2/sparc/libc-5.3.12-18.4.sparc.rpm rpm -Uvh ftp://updates.redhat.com/4.2/sparc/libc-debug-5.3.12-18.4.sparc.rpm rpm -Uvh ftp://updates.redhat.com/4.2/sparc/libc-devel-5.3.12-18.4.sparc.rpm rpm -Uvh ftp://updates.redhat.com/4.2/sparc/libc-profile-5.3.12-18.4.sparc.rpm rpm -Uvh ftp://updates.redhat.com/4.2/sparc/libc-static-5.3.12-18.4.sparc.rpm Source rpm: rpm -Uvh ftp://updates.redhat.com/4.2/SRPMS/libc-5.3.12-18.4.src.rpm Red Hat Linux 5.0, 5.1 and 5.2: =============================== i386: rpm -Uvh ftp://updates.redhat.com/5.2/i386/libc-5.3.12-28.i386.rpm Source rpm: rpm -Uvh ftp://updates.redhat.com/5.2/SRPMS/libc-5.3.12-28.src.rpm -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBNkt8xfGvxKXU9NkBAQEBuAP8DosSXiiNA5Yi95FpbPtxgBbtzUDHYtfE 8K3mRN2gyXY1LRshUSL1NW8Hxy16+8Y+kKHsBXH9sf4aNqwiEYzV5w+ZjOVIIEVb xEQOEFMOg6Apni5Zzdct5J4RQuFhH59CCsroacfOVtN0CeqBSKQUenDAJD5F6uod 63xM/eDSqmY= =WVg+ -----END PGP SIGNATURE-----
