Debian: New xpdf packages fix multiple vulnerabilities
by Patrick Lenz, in Security - Mon, Apr 7th 2008 03:35 UTC
Alin Rad Pop (Secunia) discovered a number of vulnerabilities in xpdf, a set of tools for display and conversion of Portable Document Format (PDF) files. Inadequate DCT stream validation allows an attacker to corrupt memory and potentially execute arbitrary code by supplying a maliciously crafted PDF file. An integer overflow vulnerability in DCT stream handling could allow an attacker to overflow a heap buffer, enabling the execution of arbitrary code. A buffer overflow vulnerability in xpdf's CCITT image compression handlers allows overflow on the heap, allowing an attacker to execute arbitrary code by supplying a maliciously crafted CCITTFaxDecode filter. Fixed packages are available from security.debian.org.

Package : xpdf
Vulnerability : multiple
Problem type : local (remote)
Debian-specific: no
CVE Id(s) : CVE-2007-4352 CVE-2007-5392 CVE-2007-5393
Alin Rad Pop (Secunia) discovered a number of vulnerabilities in xpdf, a set
of tools for display and conversion of Portable Document Format (PDF) files.
The Common Vulnerabilities and Exposures project identifies the following
three problems:
CVE-2007-4352
Inadequate DCT stream validation allows an attacker to corrupt
memory and potentially execute arbitrary code by supplying a
maliciously crafted PDF file.
CVE-2007-5392
An integer overflow vulnerability in DCT stream handling could
allow an attacker to overflow a heap buffer, enabling the execution
of arbitrary code.
CVE-2007-5393
A buffer overflow vulnerability in xpdf's CCITT image compression
handlers allows overflow on the heap, allowing an attacker to
execute arbitrary code by supplying a maliciously crafted
CCITTFaxDecode filter.
For the stable distribution (etch), these problems have been fixed in
version 3.01-9.1+etch2.
For the unstable distribution (sid), these problems have been fixed in
version 3.02-1.3.
We recommend that you upgrade your xpdf packages.
