Package        : apache
Vulnerability  : buffer overflows
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0940

Two vulnerabilities have been identified in the Apache 1.3 webserver:

CAN-2004-0940

    "Crazy Einstein" has discovered a vulnerability in the
    "mod_include" module, which can cause a buffer to be overflown and
    could lead to the execution of arbitrary code.

NO VULN ID

    Larry Cashdollar has discovered a potential buffer overflow in the
    htpasswd utility, which could be exploited when user-supplied is
    passed to the program via a CGI (or PHP, or ePerl, ...) program.

For the stable distribution (woody) these problems have been fixed in
version 1.3.26-0woody6.

For the unstable distribution (sid) these problems have been fixed in
version 1.3.33-2.

We recommend that you upgrade your apache packages.
