Synopsis
The remote TencentOS Server 4 host is missing one or more security updates.Description
The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1098 advisory.Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:
CVE-2024-38441:
Netatalk before 3.2.1 has an off-by-one error and resultant heap-based buffer overflow because of setting ibuf[len] to '\0' in FPMapName in afp_mapname in etc/afpd/directory.c. 2.4.1 and 3.1.19 are also fixed versions.
CVE-2024-38440:
Netatalk before 3.2.1 has an off-by-one error, and resultant heap-based buffer overflow and segmentation violation, because of incorrectly using FPLoginExt in BN_bin2bn in etc/uams/uams_dhx_pam.c. The original issue 1097 report stated: 'The latest version of Netatalk (v3.2.0) contains a security vulnerability. This vulnerability arises due to a lack of validation for the length field after parsing user-provided data, leading to an out-of-bounds heap write of one byte (\0). Under specific configurations, this can result in reading metadata of the next heap block, potentially causing a Denial of Service (DoS) under certain heap layouts or with ASAN enabled. ... The vulnerability is located in the FPLoginExt operation of Netatalk, in the BN_bin2bn function found in /etc/uams/uams_dhx_pam.c ... if (!(bn = BN_bin2bn((unsigned char *)ibuf, KEYSIZE, NULL))) ... threads ... [#0] Id 1, Name: afpd, stopped 0x7ffff4304e58 in ?? (), reason: SIGSEGV ... [#0] 0x7ffff4304e58 mov BYTE PTR [r14+0x8], 0x0 ... mov rdx, QWORD PTR [rsp+0x18] ...

CVE-2024-38439:
Netatalk before 3.2.1 has an off-by-one error and resultant heap-based buffer overflow because of setting ibuf[PASSWDLEN] to '\0' in FPLoginExt in login in etc/uams/uams_pam.c. 2.4.1 and 3.1.19 are also fixed versions.
