Vulnerability Assessment Summary
DSA-967-1 elog

Detailed Explanation for this Vulnerability Assessment

Several security problems have been found in elog, an electronic logbook
to manage notes. The Common Vulnerabilities and Exposures Project
identifies the following problems:
"GroundZero Security" discovered that elog insufficiently checks the
size of a buffer used for processing URL parameters, which might lead
to the execution of arbitrary code.
It was discovered that elog contains a directory traveral vulnerability
in the processing of "../" sequences in URLs, which might lead to
information disclosure.
The code to write the log file contained a format string vulnerability,
which might lead to the execution of arbitrary code.
Overly long revision attributes might trigger a crash due to a buffer
overflow.
The code to write the log file does not enforce bounds checks properly,
which might lead to the execution of arbitrary code.
elog emitted different errors messages for invalid passwords and invalid
users, which permits a possible hacker to probe for valid user names.
A possible hacker could be driven into infinite redirection with a crafted
"fail" request, which has denial of service potential.
The old stable distribution (woody) does not contain elog packages.
For the stable distribution (sarge) these problems have been fixed in
version 2.5.7+r1558-4+sarge2.
For the unstable distribution (sid) these problems have been fixed in
version 2.6.1+r1642-1.
We recommend that you upgrade your elog package.
