Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU110099

Risk: High

CVSSv4.0: N/A

CVE-ID: CVE-2015-8982

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error when processing a long string, which triggers a stack-based buffer overflow. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

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

Mitigation

Update the affected package glibc to the latest version.

2) Heap-based buffer overflow

EUVDB-ID: #VU110098

Risk: High

CVSSv4.0: N/A

CVE-ID: CVE-2015-8983

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22. A remote attacker can use vectors related to computing a size in bytes to trigger a 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.

Mitigation

Update the affected package glibc to the latest version.

3) Off-by-one

EUVDB-ID: #VU61293

Risk: High

CVSSv4.0: 8.1 [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/E:U/U:Amber]

CVE-ID: CVE-2021-3999

CWE-ID: CWE-193 - Off-by-one Error

Exploit availability: No

Description

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

The vulnerability exists due to an off-by-one error glibc getcwd() function. A remote attacker can pass specially crafted input to the application that is using the affected library version, trigger an off-by-one error and execute arbitrary code on the target system.


Mitigation

Update the affected package glibc to the latest version.
