The s_mp_div function in Mozilla Network Security Services (NSS) before 3.21, improperly divides numbers, which might make it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging use of the (1) mp_div or (2) mp_exptmod function.
For the oldoldstable distribution (squeeze), these problem has been fixed in version 3.12.8-1+squeeze14.
We recommend that you upgrade your nss packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
