Summary
perl vulnerabilities
Details
It was discovered that Perl incorrectly handled certain regular expressions. An attacker could possibly use this issue to cause Perl to hang, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2015-8853)
It was discovered that Perl incorrectly loaded libraries from the current working directory. A local attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-6185)
It was discovered that Perl incorrectly handled the rmtree and remove_tree functions. A local attacker could possibly use this issue to set the mode on arbitrary files. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-6512)
Brian Carpenter 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 has only been addressed in Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2018-6797)
Nguyen Duc Manh 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 and Ubuntu 17.10. (CVE-2018-6798)
GwanYeong Kim discovered that Perl incorrectly handled certain data when using the pack function. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-6913)

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.
