What is CVE-2015-0287?

CVE-2015-0287 is a medium-severity memory corruption vulnerability in Openssl Openssl, published on 19 Mar 2015. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a does not reinitialize CHOICE and ADB data structures, which might allow attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse.

Weakness: CWE-17
