Problem Description The xdrmem_getbytes() function in the XDR library provided by Sun Microsystems contains an integer overflow that can lead to improperly sized dynamic memory allocation. 2. Vulnerable Supported Versions System Package ---------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to glibc-2.2.4-26.i386.rpm prior to glibc-devel-2.2.4-26.i386.rpm prior to glibc-devel-static-2.2.4-26.i386.rpm prior to glibc-localedata-2.2.4-26.i386.rpm OpenLinux 3.1.1 Workstation prior to glibc-2.2.4-26.i386.rpm prior to glibc-devel-2.2.4-26.i386.rpm prior to glibc-devel-static-2.2.4-26.i386.rpm prior to glibc-localedata-2.2.4-26.i386.rpm OpenLinux 3.1 Server prior to glibc-2.2.4-26.i386.rpm prior to glibc-devel-2.2.4-26.i386.rpm prior to glibc-devel-static-2.2.4-26.i386.rpm prior to glibc-localedata-2.2.4-26.i386.rpm OpenLinux 3.1 Workstation prior to glibc-2.2.4-26.i386.rpm prior to glibc-devel-2.2.4-26.i386.rpm prior to glibc-devel-static-2.2.4-26.i386.rpm prior to glibc-localedata-2.2.4-26.i386.rpm 3. Solution The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand. 4.
