CVE-ID: CVE-2018-18751
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists due to a double-free condition that exists in the default_add_messagefunction, as defined in the read-catalog.c source code file that is related to an invalid-free condition in the po_gram_parse function, in the po-gram-gen.ysource code file. A local attacker can execute the msgfmt --check command on a file that submits malicious input and cause the service to crash.
MitigationUpdate the affected package gettext-runtime to the latest version.
