Date : 2015-01-20
CVE-ID : CVE-2015-1182
Package : polarssl
Type : remote code execution
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package polarssl before version 1.3.9-2 is vulnerable to remote code
Upgrade to 1.3.9-2.
# pacman -Syu "polarssl>=1.3.9-2"
The problem has not been fixed upstream yet.
During the parsing of a ASN.1 sequence, a pointer in the linked list of
asn1_sequence is not initialized by asn1_get_sequence_of(). In case an
error occurs during parsing of the list, a situation is created where
the uninitialized pointer is passed to polarssl_free().
This sequence can be triggered when a PolarSSL entity is parsing a
certificate. So practically this means clients when receiving a
certificate from the server or servers in case they are actively asking
for a client certificate.
An attacker may be able to remotely execute arbitrary code on the
