libsolv security update

Details

A free package dependency solver using a satisfiability algorithm. The library is based on two major, but independent, blocks:

Security Fix(es):

Two heap-overflow vulnerabilities exist in openSUSE/libsolv libsolv through 13 Dec 2020 in the decisionmap variable via the resolve_dependencies function at src/solver.c (line 1940 & line 1995), which could cause a remote Denial of Service.(CVE-2021-44568)

A heap overflow vulnerability exisfts in openSUSE libsolv through 13 Dec 2020 in the prefer_suggested function at src/policy.c: line 442.(CVE-2021-44571)

Two heap-overflow vulnerabilities exist in openSUSE libsolv through 13 Dec 2020 bugs in the propagate function at src/solver.c: line 490 and 524.(CVE-2021-44577)

Two heap overflow vulnerabilities exist in oenSUSE libsolv through 13 Dec 2020 in the resolve_installed function at src/solver.c: line 1728 & 1766.(CVE-2021-44573)

A heap-overflow vulnerability exists in openSUSE libsolv through 13 Dec 2020 in the resolve_jobrules function at src/solver.c at line 1599.(CVE-2021-44574)
