Security Fix(es):
aspell: objstack in GNU Aspell 0.60.8 has a heap-based buffer overflow in acommon::ObjStack::dup_top (called from acommon::StringMap::add and acommon::Config::lookup_list).(CVE-2019-25051)
aspell: bugfix
patch: A flaw was found in GNU patch through version 2.7.6. An ed-style diff payload patch file with shell metacharacters can be used to inject OS shell commands into a system. The ed editor does not need to be present on the vulnerable system for this attack to function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2019-13638)
patch: GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.(CVE-2018-1000156)
patch: A double-free flaw was found in the way the patch utility processed patch files. An attacker could potentially use this flaw to crash the patch utility by tricking it into processing crafted patches.(CVE-2018-6952)
patch: A NULL pointer dereference flaw was found in the way patch processed patch files. An attacker could potentially use this flaw to crash patch by tricking it into processing crafted patches.(CVE-2018-6951)
patch: bugfix
