Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2017-5953)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
vim before patch 8.0.0322 does not properly validate values for tree length when handling a spell file, which may result in an integer overflow at a memory allocation site and a resultant buffer overflow.
2) Integer overflow (CVE-ID: CVE-2017-5953)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
vim before patch 8.0.0322 does not properly validate values for tree length when handling a spell file, which may result in an integer overflow at a memory allocation site and a resultant buffer overflow.
3) Integer overflow (CVE-ID: CVE-2017-6349)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.
4) Integer overflow (CVE-ID: CVE-2017-6349)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.
5) Integer overflow (CVE-ID: CVE-2017-6350)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when reading undo files. A remote attacker can trick the victim to open a specially crafted undo file, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
