Ubuntu Update for Linux kernel vulnerabilities USN-1056-1
Vulnerability Insight:
Charlie Miller discovered several heap overflows in PPT processing. If
a user or automated system were tricked into opening a specially crafted
PPT document, a remote attacker could execute arbitrary code with user
privileges. Ubuntu 10.10 was not affected. (CVE-2010-2935, CVE-2010-2936)
Marc Schoenefeld discovered that directory traversal was not correctly
handled in XSLT, OXT, JAR, or ZIP files. If a user or automated system
were tricked into opening a specially crafted document, a remote attacker
overwrite arbitrary files, possibly leading to arbitrary code execution
with user privileges. (CVE-2010-3450)
Dan Rosenberg discovered multiple heap overflows in RTF and DOC
processing. If a user or automated system were tricked into opening a
specially crafted RTF or DOC document, a remote attacker could execute
arbitrary code with user privileges. (CVE-2010-3451, CVE-2010-3452,
CVE-2010-3453, CVE-2010-3454)
Dmitri Gribenko discovered that OpenOffice.org did not correctly
handle LD_LIBRARY_PATH in various tools. If a local attacker
tricked a user or automated system into using OpenOffice.org from an
attacker-controlled directory, they could execute arbitrary code with
user privileges. (CVE-2010-3689)
Marc Schoenefeld discovered that OpenOffice.org did not correctly process
PNG images. If a user or automated system were tricked into opening a
specially crafted document, a remote attacker could execute arbitrary
code with user privileges. (CVE-2010-4253)
It was discovered that OpenOffice.org did not correctly process TGA
images. If a user or automated system were tricked into opening a
specially crafted document, a remote attacker could execute arbitrary
code with user privileges. (CVE-2010-4643)
