OVERVIEW
f5 have released a number of HotFixes for BIG-IP correcting a number
of security vulnerabilities.
IMPACT
The vendor has provided the following information regarding these
HotFixes and their associated vulnerabilities:
libpng vulnerability CVE-2009-0040
"The PNG reference library (libpng), as used in pngcrush and other
applications, allows context-dependent attackers to cause a denial
of service (application crash) or possibly execute arbitrary code
via a crafted PNG file that triggers a free of an uninitialized
pointer." [1]
icclib vulnerabilities CVE-2009-0583, and CVE-2009-0584
"Multiple integer overflow flaws which could lead to heap-based
buffer overflows, as well as multiple insufficient input validation
flaws, were found in Ghostscript's International Color Consortium
Format library (icclib). Using specially-crafted ICC profiles, an
attacker could create a malicious PostScript or PDF file with
embedded images which could cause Ghostscript to crash, or,
potentially, execute arbitrary code when opened by the victim." [2]
BIG-IP ASM and PSM remote buffer overflow exploit
"The BIG-IP Application Security Manager (ASM) and Protocol
Security Manager (PSM) bd daemon is vulnerable to a remote buffer
overflow which may cause the system to crash and dump core." [3]
BIND vulnerability CVE-2009-0696
"F5 Networks has determined BIG-IP GTM software is vulnerable to
the malicious dynamic update message described in CVE-2009-0696.
This vulnerability is mitigated by the fact that BIND will
immediately restart after the crash. However, an attacker could
sustain an outage by continuing to send malicious packets." [4]
MITIGATION
BIG-IP version 10.0.0 HF3 corrects the libpng, icclib and ASM/PSM
buffer overflow vulnerabilities.
BIG-IP version 9.4.7 HF2 corrects the BIND and ASM/PSM buffer
overflow vulnerabilities.
BIG-IP version 9.4.6 HF3 corrects the BIND and ASM/PSM buffer
overflow vulnerabilities.
BIG-IP version 9.4.5 HF3 corrects BIND vulnerability.
These HotFixes are available for download from the vendor's
