Security Advisory

1) Out-of-bounds write

Severity: Low

CVSSv3: 7.7 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2018-19198

CWE-ID: CWE-787 - Out-of-bounds Write

Description

The vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.

The vulnerability exists due to out-of-bounds write in the uriComposeQuery* and uriComposeQueryEx* functions, as defined in the UriQuery.csource code file. A local attacker can send a specially request that submits malicious input, trigger memory corruption to cause a DoS condition or execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update the affected packages.

Vulnerable software versions

uriparser: 0.3, 0.3.1, 0.3.2, 0.3.3, 0.3.4, 0.4, 0.5, 0.5.1, 0.5.2, 0.6, 0.6.1, 0.6.2, 0.6.3, 0.6.4, 0.7, 0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.7.5, 0.7.6, 0.7.7, 0.7.8, 0.7.9, 0.8, 0.8.0.1, 0.8.1, 0.8.2, 0.8.3, 0.8.4, 0.8.5, 0.8.6

2) Integer overflow

Severity: Low

CVSSv3: 7.7 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2018-19199

CWE-ID: CWE-190 - Integer Overflow or Wraparound

Description

The vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in the uriComposeQuery*and uriComposeQueryEx* functions, as defined in the UriQuery.c source code file. A local attacker can send a specially request that submits malicious input, trigger memory corruption to cause a DoS condition or execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

3) Null pointer dereference

Severity: Low

CVSSv3: 2.9 [CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-19200

CWE-ID: CWE-476 - NULL Pointer Dereference

Description

The vulnerability allows a local attacker to cause DoS condition on the target system.

The vulnerability exists in the uriResetUri* function, as defined in the UriCommon.c source code file due to the allowance of operations on a NULL input. A local attacker can send a specially request that submits malicious input, trigger NULL pointer dereference to cause a DoS condition.

Mitigation

Update the affected packages.

4) Out-of-bounds read

Severity: Low

CVSSv3: 6.7 [CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C] [PCI]

CVE-ID: CVE-2018-20721

CWE-ID: CWE-125 - Out-of-bounds Read

Description

The vulnerability allows a remote attacker to gain access to cause DoS condition.

The vulnerability exists in URI_FUNC() in UriParse.c in uriparser due to a boundary condition. A remote attacker can create a specially crafted Excel file, trick the victim into opening it, trigger out-of-bounds read error for an incomplete URI with an IPv6 address containing an embedded IPv4 address, such as a "//[::44.1" address and cause the service to crash.

Mitigation

Update the affected packages.
