TencentOS Server 3: libtiff (TSSA-2023:0009)

medium Nessus Plugin ID 238621

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0009 advisory.

 Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

 CVE-2022-2867:
 libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.

 CVE-2022-2868:
 libtiff's tiffcrop utility has a improper input validation flaw that can lead to out of bounds read and ultimately cause a crash if an attacker is able to supply a crafted file to tiffcrop.

 CVE-2022-2869:
 libtiff's tiffcrop utility has a improper input validation flaw that can lead to out of bounds read and ultimately cause a crash if an attacker is able to supply a crafted file to tiffcrop.

 CVE-2022-2056:
 Divide By Zero error in tiffcrop in libtiff 4.4.0 allows attackers to cause a denial-of-service via a crafted tiff file. For users that compile libtiff from sources, the fix is available with commit f3a5e010.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
