Echo: curl-8.8.0: security update to 8.8.0+e1

high Tenable Cloud Security Plugin ID 476269

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect
 an invalid field and return error. Unfortunately, when doing so it also invokes `free()` on a 4 byte
 localstack buffer. Most modern malloc implementations detect this error and immediately abort. Some
 however accept the input pointer and add that memory to its list of available chunks. This leads to the
 overwriting of nearby stack memory. The content of the overwrite is decided by the `free()`
 implementation; likely to be memory pointers and a set of flags. The most likely outcome of exploting this
 flaw is a crash, although it cannot be ruled out that more serious results can be had in special
 circumstances. (CVE-2024-6197)

Solution

Update the curl-8.8.0 library and its related packages to version 8.8.0+e1 or later.
