Remote exploitation of an input validation error in the uudecoding
feature of Adobe Acrobat Reader (Unix) 5.0 allows an attacker to
execute arbitrary code.

The Unix and Linux versions of Adobe Acrobat Reader 5.0 automatically
attempt to convert uuencoded documents back into their original
format. The vulnerability specifically exists in the failure of
Acrobat Reader to check for the backtick shell metacharacter in the
filename before executing a command with a shell. This allows a
maliciously constructed filename to execute arbitrary programs."

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 CVE-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 CVE-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."

"The remote host is affected by the vulnerability described in GLSA-200408-14
(acroread: UUDecode filename buffer overflow)

    acroread contains two errors in the handling of UUEncoded filenames.
    First, it fails to check the length of a filename before copying it
    into a fixed size buffer and, secondly, it fails to check for the
    backtick shell metacharacter in the filename before executing a command
    with a shell.
  
Impact :

    By enticing a user to open a PDF with a specially crafted filename, an
    attacker could execute arbitrary code or programs with the permissions
    of the user running acroread.
  
Workaround :

    There is no known workaround at this time. All users are encouraged to
    upgrade to the latest available version of acroread."
