[slackware-security] apache (SSA:2004-133-01)
New apache packages are available for Slackware 8.1, 9.0, 9.1, and -current to
fix security issues. These include a possible denial-of-service attack as well
as the ability to possible pipe shell escapes through Apache's errorlog (which
could create an exploit if the error log is read in a terminal program that
does not filter such escapes). We recommend that sites running Apache upgrade
to the new Apache package.
More details about these issues may be found in the Common
Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 9.1 ChangeLog:
+--------------------------+
Wed May 12 13:06:39 PDT 2004
patches/packages/apache-1.3.29-i486-2.tgz: Patched four security issues
in the Apache web server as noted on http://httpd.apache.org.
These security fixes were backported from Apache 1.3.31:
In mod_digest, verify whether the nonce returned in the client
response is one we issued ourselves. This problem does not affect
mod_auth_digest. (CAN-2003-0987)
Escape arbitrary data before writing into the errorlog. (CAN-2003-0020)
Fix starvation issue on listening sockets where a short-lived connection
on a rarely-accessed listening socket will cause a child to hold the
accept mutex and block out new connections until another connection
arrives on that rarely-accessed listening socket. (CAN-2004-0174)
Fix parsing of Allow/Deny rules using IP addresses without a netmask;
issue is only known to affect big-endian 64-bit platforms (CAN-2003-0993)
For more details, see:
