Severity
Summary
PostgreSQL before 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 allows remote authenticated users to cause a denial of service (stack consumption and crash) by triggering a failure in the conversion of a localized error message to a client-specified encoding, as demonstrated using mismatched encoding conversion requests.

In older releases\r\nit is necessary to select a locale and client encoding for which\r\nspecific messages fail to translate, and so a given installation may or\r\nmay not be vulnerable depending on the administrator-determined locale\r\nsetting.\r\n\r\nReleases 8.3.7, 8.2.13, 8.1.17, 8.0.21, and 7.4.25 are secure against\r\nall known variants of this issue.\"",

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
