Debian: New emil packages fix multiple vulnerabilities

Ulf Harnhammar discovered a number of vulnerabilities in emil, a filter for converting Internet mail messages. Buffer overflows have been identified in the encode_mime function, the encode_uuencode function, and the decode_uuencode function. These bugs could allow a carefully crafted email message to cause the execution of arbitrary code supplied with the message when it is acted upon by emil. Additionally, format string bugs in statements which print various error messages have been found. The exploit potential of these bugs has not been established, and is probably configuration-dependent. Fixed packages are available from security.debian.org.

Package        : emil
Vulnerability  : several
Problem-Type   : local/remote
Debian-specific: no
CVE Ids        : CAN-2004-0152 CAN-2004-0153

Ulf Harnhammar discovered a number of vulnerabilities in emil, a
filter for converting Internet mail messages.  The vulnerabilities
fall into two categories:

 - CAN-2004-0152 - Buffer overflows in (1) the encode_mime function,
   (2) the encode_uuencode function, (3) the decode_uuencode
   function.  These bugs could allow a carefully crafted email message
   to cause the execution of arbitrary code supplied with the message
   when it is acted upon by emil.

 - CAN-2004-0153 - Format string bugs in statements which print
   various error messages.  The exploit potential of these bugs has
   not been established, and is probably configuration-dependent.

For the stable distribution (woody) these problems have been fixed in
version 2.1.0-beta9-11woody1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you update your emil package.
