CVE-2022-40299
In Singular before 4.3.1, a predictable /tmp pathname is used (e.g., by sdb.cc), which allows local users to gain the privileges of other users via a procedure in a file under /tmp.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Singular before 4.3.1, a predictable /tmp pathname is used (e.g., by sdb.cc), which allows local users to gain the privileges of other users via a procedure in a file under /tmp. NOTE: this CVE Record is about sdb.cc and similar files in the Singular interface that have predictable /tmp pathnames; this CVE Record is not about the lack of a safe temporary-file creation capability in the Singular language.
