Description

This security bulletin contains information about 2 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2015-7499)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the xmlGROW function in parser.c in libxml2 before 2.9.3. A remote attacker can use unspecified vectors. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Buffer overflow (CVE-ID: CVE-2015-8710)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The htmlParseComment function in HTMLparser.c in libxml2 allows attackers to obtain sensitive information, cause a denial of service (out-of-bounds heap memory access and application crash), or possibly have unspecified other impact via an unclosed HTML comment.
