An internal reference count is held on the buffer pool, incremented every time a new buffer is created from the pool. The reference count is maintained as an int; on LP64 systems this can cause the reference count to overflow if the client creates a large number of wl_shm buffer objects, or if it can coerce the server to create a large number of external

Mageia 2022-0417: pcre security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT. (CVE-2022-1586)

Mageia 2022-0415: mbedtls security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

An unauthenticated remote host could send an invalid ClientHello message in which the declared length of the cookie extends past the end of the message. A DTLS server with MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled would read past the end of the message up to the declared length of the cookie. This could cause a buffer overread of up to 255 bytes on the heap in vulnerable DTLS

Mageia 2022-0413: 389-ds-base security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A flaw was found In 389-ds-base. When the Content Synchronization plugin is enabled, an authenticated user can reach a NULL pointer dereference using a specially crafted query. This flaw allows an authenticated ttacker to cause a denial of service. This CVE is assigned against an incomplete fix of CVE-2021-3514. (CVE-2022-2850)

Mageia 2022-0410: libtiff security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

There is a double free or corruption in rotateImage() at tiffcrop.c:8839 found in libtiff 4.4.0rc1. (CVE-2022-2519) A flaw was found in libtiff 4.4.0rc1. There is a sysmalloc assertion fail in rotateImage() at tiffcrop.c:8621 that can cause program crash when

Mageia 2022-0406: php security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

GD - Fixed bug #81739: OOB read due to insufficient input validation in imageloadfont(). Hash - Fixed bug #81738: buffer overflow in hash_update() on long parameter. Session - Fixed bug GH-9583 (session_create_id() fails with user defined

Mageia 2022-0405: curl security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

When doing HTTP(S) transfers, libcurl might erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously was used to issue a PUT request which used that callback. (CVE-2022-32221)

Mageia 2022-0403: nbd security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

It was discovered that nbd prior to 3.24 contained an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name resulting in a write to a dangling pointer (CVE-2022-26495).
