A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted file containing negative size values in the function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).
