CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 2CVE-2021-4156 – libsndfile: heap out-of-bounds read in src/flac.c in flac_buffer_copy
https://notcve.org/view.php?id=CVE-2021-4156
An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws. Se ha encontrado un fallo de lectura fuera de límites en la funcionalidad del códec FLAC de libsndfile. Un atacante que sea capaz de enviar un archivo especialmente diseñado (por medio de engañar a un usuario para que lo abra o de otro modo) a una aplicación enlazada con libsndfile y que use el códec FLAC, podría desencadenar una lectura fuera de límites que muy probablemente causaría un fallo, pero podría filtrar información de la memoria que podría usarse en una explotación posterior de otros fallos • https://bugzilla.redhat.com/show_bug.cgi?id=2027690 https://github.com/libsndfile/libsndfile/issues/731 https://github.com/libsndfile/libsndfile/pull/732/commits/4c30646abf7834e406f7e2429c70bc254e18beab https://lists.debian.org/debian-lts-announce/2022/06/msg00020.html https://lists.debian.org/debian-lts-announce/2022/09/msg00036.html https://security.gentoo.org/glsa/202309-11 https://access.redhat.com/security/cve/CVE-2021-4156 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-24764 – Stack buffer overflow in pjproject
https://notcve.org/view.php?id=CVE-2022-24764
PJSIP is a free and open source multimedia communication library written in C. Versions 2.12 and prior contain a stack buffer overflow vulnerability that affects PJSUA2 users or users that call the API `pjmedia_sdp_print(), pjmedia_sdp_media_print()`. Applications that do not use PJSUA2 and do not directly call `pjmedia_sdp_print()` or `pjmedia_sdp_media_print()` should not be affected. A patch is available on the `master` branch of the `pjsip/pjproject` GitHub repository. There are currently no known workarounds. • https://github.com/pjsip/pjproject/commit/560a1346f87aabe126509bb24930106dea292b00 https://github.com/pjsip/pjproject/security/advisories/GHSA-f5qg-pqcg-765m https://lists.debian.org/debian-lts-announce/2022/03/msg00035.html https://lists.debian.org/debian-lts-announce/2022/11/msg00021.html https://lists.debian.org/debian-lts-announce/2023/08/msg00038.html https://security.gentoo.org/glsa/202210-37 https://www.debian.org/security/2022/dsa-5285 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
