(RHSA-2004:432) acroread security update

The Adobe Acrobat Reader browser allows for the viewing, distributing, and
printing of documents in portable document format (PDF).

iDEFENSE has reported that Adobe Acrobat Reader 5.0 contains a buffer
overflow when decoding uuencoded documents. An attacker could execute
arbitrary code on a victim’s machine if a user opens a specially crafted
uuencoded document. This issue poses the threat of remote execution, since
Acrobat Reader may be the default handler for PDF files. The Common
Vulnerabilities and Exposures project has assigned the name CAN-2004-0631
to this issue.

iDEFENSE also reported that Adobe Acrobat Reader 5.0 contains an input
validation error in its uuencoding feature. An attacker could create a
file with a specially crafted file name which could lead to arbitrary
command execution on a victim’s machine. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2004-0630 to this issue.

All users of Acrobat Reader are advised to upgrade to this updated package,
which is not vulnerable to these issues.
