Problem Description iDEFENSE has identified a Buffer Overflow vulnerability in SCO Unixware ppp prompt. Local exploitation of a buffer overflow vulnerability in the ppp binary, allows attackers to gain root privileges. This could lead to the execution of arbitrary code with root privileges, as ppp is setuid root by default. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2005-2927 to this issue. 2. Vulnerable Supported Versions System Binaries ---------------------------------------------------------------------- UnixWare 7.1.4 /usr/bin/ppptalk UnixWare 7.1.3 /usr/bin/ppptalk 3. Solution The proper solution is to install the latest packages. 4. UnixWare 7.1.4 4.1 Location of Fixed Binaries ftp://ftp.sco.com/pub/updates/UnixWare/SCOSA-2005.41 4.2 Verification MD5 (erg712940.uw714.pkg.Z) = d47a9958e6dfd44c9b95e1d9489011f4 md5 is available for download from ftp://ftp.sco.com/pub/security/tools 4.3 Installing Fixed Binaries Upgrade the affected binaries with the following sequence: Download erg712940.uw714.pkg.Z to the /var/spool/pkg directory # uncompress /var/spool/pkg/erg712940.uw714.pkg.Z # pkgadd -d /var/spool/pkg/erg712940.uw714.pkg 5.
