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.

Buffer overflow vulnerability in function prune_to_recommended in src/policy.c in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

Buffer overflow vulnerability in function pool_installable_whatprovides in src/repo.h in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

Buffer overflow vulnerability in function pool_disabled_solvable in src/repo.h in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

Buffer overflow vulnerability in function pool_installable in src/repo.h in libsolv before 0.7.17 allows attackers to cause a Denial of Service.

Buffer overflow vulnerability in libsolv 2020-12-13 via the Solver * testcase_read(Pool *pool, FILE *fp, const char *testcase, Queue *job, char **resultp, int *resultflagsp function at src/testcase.c: line 2334, which could cause a denial of service

repodata_schema2id in repodata.c in libsolv before 0.7.6 has a heap-based buffer over-read via a last schema whose length is less than the length of the input schema.

There is an illegal address access at ext/testcase.c in libsolv.a in libsolv through 0.7.2 that will cause a denial of service. NOTE: third parties dispute this issue stating that the issue affects the test suite and not the underlying library. It cannot be exploited in any real-world application

There is a NULL pointer dereference at ext/testcase.c (function testcase_str2dep_complex) in libsolvext.a in libsolv through 0.7.2 that will cause a denial of service.
