EulerOS 2.0 SP9 : glibc (EulerOS-SA-2024-1932)

high Nessus Plugin ID 202522

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the glibc packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 The iconv() function in the GNU C Library versions 2.39 and older may overflow the output buffer passed to it by up to 4 bytes when converting strings to the ISO-2022-CN-EXT character set, which may be used to crash an application or overwrite a neighbouring variable.(CVE-2024-2961)

 nscd: Stack-based buffer overflow in netgroup cache.If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted by client requests then a subsequent client request for netgroup data may result in a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33599)

 nscd: netgroup cache may terminate daemon on memory allocation failure.The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or xrealloc and these functions may terminate the process due to a memory allocation failure resulting in a denial of service to the clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33601)

 nscd: Null pointer crashes after notfound response.If the Name Service Cache Daemon's (nscd) cache fails to add a not-found netgroup response to the cache, the client request can result in a null pointer dereference. This flaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33600)

 nscd: netgroup cache assumes NSS callback uses in-buffer strings.The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer.The flaw was introduced in glibc 2.15 when the cache was added to nscd.This vulnerability is only present in the nscd binary.(CVE-2024-33602)

Tenable has extracted the preceding description block directly from the EulerOS glibc 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 glibc packages.
