UBUNTU-CVE-2026-57433 (CVE-2026-57433)

Vulnerability from osv_ubuntu – Published: 2026-07-13 17:17 – Updated: 2026-09-09 22:35 – Source website

Details

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record. retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value. A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.

Severity

9.8 (Critical)

USN-8675-1 (UBUNTU-CVE-2026-12087)

Vulnerability from osv_ubuntu – Published: 2026-08-25 14:55 – Updated: 2026-08-25 14:55 – Source website

Summary

perl vulnerabilities

Details

It was discovered that Perl incorrectly handled short source addresses in the Socket module. An attacker could possibly use this issue to trigger an out-of-bounds heap read, resulting in information disclosure. (CVE-2026-12087)

It was discovered that Perl incorrectly handled regular expressions containing a large number of fixed string alternatives. An attacker could possibly use this issue to cause incorrect regular expression matches, resulting in security restrictions being bypassed. (CVE-2026-13221)

It was discovered that Perl incorrectly handled certain large repeat counts when processing pack and unpack templates. An attacker could possibly use this issue to trigger an out-of-bounds heap read, resulting in information disclosure. (CVE-2026-57432)

It was discovered that Perl incorrectly handled certain crafted data when deserializing with the Storable module. An attacker could possibly use this issue to trigger an integer overflow and application termination, resulting in a denial of service. (CVE-2026-57433)

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.
