Description
This security bulletin contains information about 3 vulnerabilities.
1) Infinite loop (CVE-ID: CVE-2020-7595)
CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
CVSSv4: 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
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in xmlStringLenDecodeEntities in parser.c. A remote attacker can consume all available system resources and cause denial of service conditions in a certain end-of-file situation.
2) Memory leak (CVE-ID: CVE-2019-20388)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 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
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in xmlSchemaPreRun in xmlschemas.c. A remote attacker can trigger a xmlSchemaValidateStream memory leak and perform denial of service attack.
3) Memory leak (CVE-ID: CVE-2019-19956)
CWE-ID: CWE-401 - Missing release of memory after effective lifetime
CVSSv4: 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
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in xmlParseBalancedChunkMemoryRecover in parser.c. A remote attacker can trigger a memory leak related to newDoc->oldNs and perform denial of service attack.
