CVE-2026-57433 (GCVE-0-2026-57433)

Vulnerability from cvelistv5 – Published: 2026-07-13 15:37 – Updated: 2026-07-14 13:36

Title

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record

Summary

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)

GHSA-R969-GF4C-XQF7

Vulnerability from github – Published: 2026-07-13 18:30 – Updated: 2026-07-14 15:32

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)

Vulnerability from osv_openeuler – Published: 2026-08-01 11:12 – Updated: 2026-08-06 11:12 – Source website

Summary

perl security update

Details

Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.

Security Fix(es):

Perl versions through 5.43.10 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack.

S_measure_struct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds.

A template derived from untrusted input can read heap memory past the buffer and return it to the caller.(CVE-2026-57432)

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.(CVE-2026-57433)

Severity

9.8 (Critical)

  "details": "Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.\r\n\r\nSecurity Fix(es):\n\nPerl versions through 5.43.10 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack.\n\nS_measure_struct adds each item\u0026apos;s size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds.\n\nA template derived from untrusted input can read heap memory past the buffer and return it to the caller.(CVE-2026-57432)\n\nStorable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.\n\nretrieve_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.\n\nA crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.(CVE-2026-57433)",
