Debian Security Advisory
DSA-967-1 elog -- several vulnerabilities
- Date Reported:
- 10 Feb 2006
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 349528.
In Mitre's CVE dictionary: CVE-2005-4439, CVE-2006-0347, CVE-2006-0348, CVE-2006-0597, CVE-2006-0598, CVE-2006-0599, CVE-2006-0600.
- More information:
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 traversal 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 allows an attacker to probe for valid user names.
An attacker 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.
