Jayakrishna Menon discovered that Perl incorrectly handled Perl_my_setenv. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-18311)
Eiichi Tsukata discovered that Perl incorrectly handled certain regular expressions. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 18.10. (CVE-2018-18312)
Eiichi Tsukata discovered that Perl incorrectly handled certain regular expressions. An attacker could use this issue to cause Perl to crash, resulting in a denial of service. (CVE-2018-18313)
Jakub Wilk discovered that Perl incorrectly handled certain regular expressions. An attacker could use this issue to cause Perl to crash, resulting in a denial of service. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 18.10. (CVE-2018-18314)

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.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
