(CVE-2015-7181, CVE-2015-7182)
A heap-based buffer overflow was found in NSPR. An attacker could use this
flaw to cause NSPR to crash or execute arbitrary code with the permissions
of the user running an application compiled against the NSPR library.
(CVE-2015-7183)
Note: Applications using NSPR's PL_ARENA_ALLOCATE, PR_ARENA_ALLOCATE,
PL_ARENA_GROW, or PR_ARENA_GROW macros need to be rebuild against the fixed
nspr packages to completely resolve the CVE-2015-7183 issue. This erratum
includes nss and nss-utils packages rebuilt against the fixed nspr version.
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Tyson Smith, David Keeler and Ryan Sleevi as the
original reporter.
All nss, nss-util and nspr users are advised to upgrade to these updated
packages, which contain backported patches to correct these issues.");
