Debian DLA-480-1 : nss security update
High Nessus Plugin ID 91242
SynopsisThe remote Debian host is missing a security update.
DescriptionThis security update fixes serious security issues in NSS including arbitrary code execution and remote denial service attacks.
For Debian 7 'wheezy', these problems have been fixed in 3.14.5-1+deb7u6. We recommend you upgrade your nss packages as soon as possible.
The sec_asn1d_parse_leaf function improperly restricts access to an unspecified data structure.
Heap-based buffer overflow in the ASN.1 decoder.
The s_mp_div function in lib/freebl/mpi/mpi.c in improperly divides numbers, which might make it easier for remote attackers to defeat cryptographic protection mechanisms.
Heap-based buffer overflow allows remote attackers to execute arbitrary code via crafted ASN.1 data in an X.509 certificate.
Use-after-free vulnerability in the ssl3_HandleECDHServerKeyExchange function allows remote attackers to cause a denial of service or possibly have unspecified other impact by making an SSL (1) DHE or (2) ECDHE handshake at a time of high memory consumption.
Use-after-free vulnerability in the PK11_ImportDERPrivateKeyInfoAndReturnKey function allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted key data with DER encoding.
