Descriptions du CVE

Integer overflow in PHP 5 up to 5.1.6 and 4 before 4.3.0 allows remote attackers to execute arbitrary code via an argument to the unserialize PHP function with a large value for the number of array elements, which triggers the overflow in the Zend Engine ecalloc function (Zend/zend_alloc.c).

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/20349/info PHP is prone to an integer-overflow vulnerability because the application fails to do proper bounds checking on user-supplied data. An attacker can exploit this vulnerability to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions. <? print_r(unserialize('a:1073741823:{i:0;s:30:"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"}')); ?> in function zend_hash_init() int overflow ( ecalloc() )-> heap overflow here segfault in zend_hash_find() but it's possible to fake the bucket and exploit a zend_hash_del_index_or_key i tried a memory dump , just fake the bucked with the pointer of the $GLOBALS's bucket but segfault before in memory_shutdown...
