Veritas Storage Foundation Memory Disclosure Vulnerability


AFFECTED: Veritas Storage Foundation 5.0

PLATFORM: Solaris, Linux, AIX, HP-UX

CLASSIFICATION: Sensitive Information Uncleared Before Release (CWE-226)

RESEARCHER: Derek Callaway

IMPACT: Data Leakage



REFERENCES: CVE-2008-3248, SYM08-018, BID 31678


Veritas Storage Foundation 5.0 from Symantec provides a complete
solution for heterogeneous online storage management. Based on the
industry-leading Veritas Volume Manager and Veritas File System, it
provides a standard set of integrated tools to centrally manage
explosive data growth, maximize storage hardware investments, provide
data protection and adapt to changing business requirements.


VxFS (VERITAS File System) is an extent based, journaling filesystem
included with Symantec's Storage Foundation Suite. It implements a
"Quick I/O for Databases" feature; the set-uid root program qiomkfile
manages special files that help to increase transaction processing
efficiency. Uninitialized chunks of memory are written to a hidden file
that qiomkfile creates at runtime. Depending on system activity prior
to invocation, the new file may contain sensitive information.


qiomkfile will write the unitialized data to a dot-file whose name is provided
as an argument. Varying the numeric values passed to qiomkfile on the
command-line through the -s and -h flags will cause disparate chunks of
file system memory to be written to the dot-file. According to C99,
( "The malloc function allocates space for an object whose
size is specified by size and whose value is indeterminate."


Remove the set-uid bit from the qiomkfile binary.

chmod u-s /opt/VRTS/bin/qiomkfile


Symantec included a fix for this problem in the recent maintenance
release Veritas Software File System 5.0 MP3.
