Description Gianluca Gabrielli 2023-07-07 09:02:28 UTC

This vulnerability allows remote attackers to execute arbitrary code on affected
installations of GStreamer. Interaction with this library is required to exploit
this vulnerability but attack vectors may vary depending on the implementation.

The specific flaw exists within the parsing of SRT subtitle files. The issue
results from the lack of proper validation of the length of user-supplied data
prior to copying it to a heap-based buffer. An attacker can leverage this
vulnerability to execute code in the context of the current process.

Comment 1 Gianluca Gabrielli 2023-07-07 09:08:14 UTC

Affected packages:

- SUSE:SLE-15-SP5:Update/gstreamer-plugins-base
- SUSE:ALP:Source:Standard:1.0/gstreamer-plugins-base
- SUSE:SLE-15-SP2:Update/gstreamer-plugins-base
- SUSE:SLE-15-SP4:Update/gstreamer-plugins-base
- SUSE:SLE-15:Update/gstreamer-plugins-base
- openSUSE:Factory/gstreamer-plugins-base
- SUSE:SLE-12-SP2:Update/gstreamer-plugins-base

The upstream patch [0] won't easily apply to `SUSE:SLE-12-SP2:Update/gstreamer-plugins-base`, hence some some adjustments are required. I believe it's affected too, as can be seen at gst/subparse/gstsubparse.c:760

```
 750   │ subrip_fix_up_markup (gchar ** p_txt)
 751   │ {
 752   │   gchar *cur, *next_tag;
 753   │   gchar open_tags[32];
 754   │   guint num_open_tags = 0;
 755   │
 756   │   g_assert (*p_txt != NULL);
 757   │
 758   │   cur = *p_txt;
 759   │   while (*cur != '\0') {
 760   │     next_tag = strchr (cur, '<');
 761   │     if (next_tag == NULL)
 762   │       break;
 763   │     ++next_tag;
 764   │     switch (*next_tag) {
```

Comment 12 Antonio Larrosa 2023-08-30 10:13:24 UTC

In SLE-12 the dvdspu directory is removed before building the package so SLE-12 isn't affected by CVE-2023-37329
