CVE-2021-3200

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

• Using a dictionary approach to store and retrieve package and dependency information.
• Using satisfiability, a well known and researched topic, for resolving package dependencies.

Security Fix(es):

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(CVE-2021-3200)

The libsolv packages provide a library for resolving package dependencies using a satisfiability algorithm.

Security Fix(es):

• libsolv: heap-based buffer overflow in testcase_read() in src/testcase.c (CVE-2021-3200)
