CVE Vulnerabilities


Use of Externally-Controlled Format String

Published: Feb 10, 2014 | Modified: Feb 13, 2023
CVSS 3.x
CVSS 2.x

Multiple format string vulnerabilities in Condor 7.2.0 through 7.6.4, and possibly certain 7.7.x versions, as used in Red Hat MRG Grid and possibly other products, allow local users to cause a denial of service (condor_schedd daemon and failure to launch jobs) and possibly execute arbitrary code via format string specifiers in (1) the reason for a hold for a job that uses an XML user log, (2) the filename of a file to be transferred, and possibly other unspecified vectors.


The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
