Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU24490
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2019-20387
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read via a last schema whose length is less than the length of the input schema. A remote attacker can perform a denial of service attack.
MitigationUpdate the affected package libsolv to the latest version.
